     DETAILED DESCRIPTION 
     To make a person skilled in the art better understand solutions of the present disclosure, certain embodiments of the present disclosure are described below with reference to the accompanying drawings. Apparently, the described embodiments are merely some rather than all of the embodiments of the present disclosure. Other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. 
     The terms such as “first” and “second” in the specification, claims, and accompanying drawings of the present disclosure that are intended to distinguish between similar objects rather than describe a particular sequence or a chronological order. It is to be understood that the data termed in such a way are interchangeable in proper circumstances, so that the embodiments of the present disclosure described herein can be implemented in other orders than the order illustrated or described herein. In addition, the terms “include” and “have” and any other variants are intended to cover the non-exclusive inclusion. For example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those expressly listed steps or units, but may include other steps or units not expressly listed or inherent to such a process, method, product, or device. 
     Technical terms involved in the embodiments of the present disclosure include the followings. 
     (1) Mobile terminal: A mobile terminal generally refers to handheld portable game devices, which include but are not limited to mobile phones. 
     (2) Creating a character appearance: This refers to a computer-readable instruction of defining the appearance of a game character or another character. A game with a massive number of fictive settings may have features such as race, gender, and other types. 
     (3) Facial recognition: The facial recognition is also referred to as face recognition, face perception, facial perception, or the like. The facial recognition uses a recognition information obtaining apparatus to obtain a face image of a recognized object. A computer system, after obtaining the image, compares the image with images in a database to complete the recognition process. 
     According to one aspect of the embodiments of the present disclosure, a method for generating a virtual operating object is provided. In an embodiment, the method for generating a virtual operating object may be applied to, but not limited to, an application environment shown in  FIG. 1 . As shown in  FIG. 1 , a target client (for example, Android, iOS, or Web) of a target application is run on a terminal device  102 . The target client may be a game application, a social media application, a video editing application, etc. Through the target client, a target portrait picture is obtained on a configuration interface of the target game application. 
     The target portrait picture is transmitted to a server  104  through a network. The server  104  may be a backend server of the target client. After receiving the target portrait picture, the server  104  obtains a first picture region of the target portrait picture where a first part presents and a first part feature of the first part according to the target portrait picture; determines a target part matching the first picture region in a pre-established feature image library, the target part being a part of a to-be-generated target virtual operating object in the target game application; and determines, in a value range of a target part feature of the target part pre-recorded in the feature image library, a target feature parameter, which matches the first part feature, of the target part feature. Further, the server  104  transmits the target feature parameter to the mobile device  102  through a network. The mobile device  102  generates the target part in the target game application according to the target feature parameter. The foregoing description is merely an example, and is not limited in this embodiment of the present disclosure. 
     In an embodiment, the target portrait picture is obtained on the configuration interface of the terminal device  102 , and then the terminal device  102  obtains the first picture region of the first part in the target portrait picture and the first part feature of the first part according to the target portrait picture; determines a target part matching the first picture region in a pre-established feature image library, the target part being a part of a to-be-generated target virtual operating object in the target game application; and determines, in the value range of the target part feature of the target part pre-recorded in the feature image library, the target feature parameter, which matches the first part feature, of the target part feature; and generates the target part in the target game application according to the target feature parameter. The foregoing description is merely an example, and is not intended to be limiting. 
     In an embodiment, the target portrait picture may be a picture directly taken by a user through a mobile device (for example, a mobile phone), or the target portrait picture may be a picture saved locally in the mobile device. 
     In an embodiment, the terminal device may be a terminal device provided with a target client, which may include: a mobile phone (for example, an Android phone or an iOS phone), a notebook computer, a tablet computer, a palmtop computer, a mobile Internet device (MID), a PAD, a desktop computer, and the like. The network may include a wired network and a wireless network. The wired network may include: a local area network, a metropolitan area network, and a wide area network. The wireless network may include: Bluetooth, Wi-Fi, and other networks implementing wireless communication. The server may be an independent server, or may be a cluster server including a plurality of servers. The foregoing description is merely an example, and is not limited herein. 
     In an embodiment, the method may be performed by a server, a terminal device, or a server and a terminal device jointly. In one embodiment, an example in which the method is performed by a terminal device (for example, the terminal device  102 ) is used for description. As shown in  FIG. 2 , the method for generating a virtual operating object may include the followings. 
     S 202 : Obtain a target portrait picture on a configuration interface of a target application. 
     S 204 : Obtain a first picture region of the target portrait picture where a first part presents and a first part feature of the first part according to the target portrait picture. 
     S 206 : Determine a target part matching the first picture region in a pre-established feature image library, the target part being a part of a to-be-generated target virtual operating object in the target application. 
     S 208 : Determine a target feature parameter matching the first part feature in a value range of a target part feature of the target part pre-recorded in the feature image library. 
     S 210 : Generate the target part in the target application according to the target feature parameter. 
     In an embodiment, the target application may be a target game application. In other embodiments, the target application may be other applications, other than the game application, in which virtual objects need to be generated. 
     In an embodiment, the method for generating a virtual operating object includes setting a game character appearance in a game scene through a client. 
     For example, after entering a target game, a user may set, on a configuration interface of the target game, a game character appearance of the user in the game. The user may select a game character appearance provided in a system of the game, but game character appearances provided in the system may have a high repetitive rate. Alternatively, the user may manually set a favorite game character appearance. 
     In an embodiment, the user may obtain a target portrait picture on the configuration interface of the target game application, and then obtain a first picture region of the target portrait picture where a first part presents (for example, eyes, a nose, eyebrows, a mouth, and ears) and a first part feature of the first part according to the obtained target portrait picture, and determine a target part matching the first picture region in a pre-established feature image library, the target part being a part of a to-be-generated target virtual operating object in the target game application, a target part feature of the target part matching the first part feature of the first part. A target feature parameter of the first part feature can be determined through a value range of the target feature of the target part. The target part is generated in the target game application according to the target feature parameter, and further a game character appearance of the target virtual operating object can be determined according to the target part. 
     In one embodiment, a target portrait picture is obtained on a configuration interface of a target game application; a first part of the target portrait picture, a first picture region of the first part, and a first part feature of the first part are obtained; a target part matching the first picture region is determined in a feature image library; a target feature parameter matching the first part feature is determined according to a value range of a target part feature of the target part in the feature image library; and finally, the target part is generated in the target game application according to the target feature parameter. With this method, a target part in a target game application can be determined through a part of a face picture. Because the target part is a part of a game character appearance, the technical effect of quickly generating different game character appearance is achieved, thereby resolving the technical problems in the related art that either only fixed game character appearance is provided or character appearance can be set only by cumbersome manual adjustment, benefiting the heterogeneous of game character appearances. 
     The method for generating a virtual operating object in one embodiment is described with reference to  FIG. 2 . 
     In S 202 , the target portrait picture is obtained on the configuration interface of the target game application. 
     In an embodiment, the target game application may be any game application in which a game character appearance of a user can be created, which is not limited herein. 
     The target portrait picture may be understood as a type of workable-picture, which may be worked on for various purposes like a raw material. The target portrait picture may be a local picture uploaded by a user (for example, a player), or a face image of a user which is directly taken by the user through a terminal device (for example, a mobile phone). For the workable-picture uploaded by the user, the terminal device or a server may check the specifications of the workable-picture, to check whether the workable-picture conforms to preset basic criteria. If the picture uploaded by the user does not conform to the criteria, the user needs to upload workable-picture again. It can be understood that the foregoing description is merely an example, and is not limited in one embodiment of the present disclosure. 
     In S 204 , the first picture region of the first part in the target portrait picture (that is, the first picture region of the target portrait picture where the first part present) and the first part feature of the first part are obtained according to the target portrait picture. 
     The target portrait picture may include one or more picture regions. Different picture regions correspond to different parts. Different parts correspond to different features. The first part may include one or more parts. For example, the first part may include eyes, eyebrows, a nose, or may include eyes, eyebrows, a nose, ears, a mouth, a face, or may include eyes only. The first part feature is used for representing feature data of the first part. For example, if the first part is eyes, the first part feature is feature data corresponding to the eyes in the target face picture. The foregoing description is merely an example, and is not limited herein. 
     In an embodiment, the first picture region of the first part and the first part feature of the first part may be obtained through an image pre-processing process, an edge detection algorithm (for example, a Canny edge detection algorithm), and other feasible manners. The first part feature may be also processed through a facial recognition algorithm. It can be understood that the foregoing description is merely an example, and is not limited in one embodiment of the present disclosure. 
     In S 206 , the target part matching the first picture region is determined in the pre-established feature image library, the target part being a part of the to-be-generated target virtual operating object in the target game application. 
     In an embodiment, the feature image library may be understood as a game character feature image library pre-established for game characters in the target game application by the terminal device or the server. 
     For example, the feature image library may be a model database (having the same function as the feature image library) established according to design requirements of the game. For example, a male database is separated from a female database. The feature image library may include a head type (ears, a nose, a mouth, eyebrows, eyes, a face contour), a skin color, a hair style, and the like. Various face parts and body parts may be further added according to different type classifications. 
     For examples, the feature image library includes the following basic types: a forehead, eyebrows, an entire nose, nasal wings, a nasal tip, a nasal bridge, a  glabella , an entire mouth, mouth corners, two sides of a lower lip, the middle of the lower lip, two sides of an upper lip, the middle of the upper lip, entire eyes, lower eyelids, outer eye corners, eyelids, eye corners, a chin, a jaw, cheek bones, a hair style, a skin color, facial accessories, entire ears (for some part types, subtypes need to be created). 
     For the feature image library, a designer may preset a massive number of models and the feature image library may be continually updated and maintained by adding a workable-picture library later. It can be understood that the foregoing description is merely an example, and is not uniquely limited in one embodiment. 
     In an embodiment, the first picture region may include a specific part of the target portrait picture (that is, the first picture region may be of or corresponding to a specific part of the target portrait picture). For example, the first picture region may be a region corresponding to the eyes part in the target portrait picture, or a region corresponding to the ears part. Through the feature image library, as shown in  FIG. 3 , the obtained first picture region is matched with model data pre-stored in the feature image library to obtain the target part matching the first picture region. The target part is pre-stored in the feature image library, and the target part is a part of the to-be-generated target virtual operating object in the target game application (for example, a game character appearance). 
     In an embodiment, the determining a target part matching the first picture region in a pre-established feature image library may include: obtaining similarity between each part recorded in the feature image library and the first part shown in the first picture region; and determining a part, similarity between which and the first part exceeds a preset threshold, in the feature image library as the target part. 
     In an embodiment, the feature image library may store picture information of each part. In a case that the first picture region is one type of picture information, similarity between picture information of the each part in the feature image library and the first part shown in the first picture region may be determined, and a part, similarity between which and the first part exceeds a preset threshold, in the feature image library is determined as the target part. Alternatively, the feature image library may further store a part feature corresponding to the each part. Similarity between the part feature of the each part in the feature image library and the first part feature of the first part may be determined, and a part corresponding to a part feature, similarity between which and the first part feature exceeds a preset threshold, in the feature image library is determined as the target part. 
     For example, a game character model is disassembled in an art image workable-material library (having the same function as the feature image library) to obtain a plurality of parts. The parts are managed in a classified manner, for example, managed according to the color, size, and height of eyes and eyebrows. Information (for example, eyes and eyebrows) of a key part (having the same function as the first part) is then extracted through an image recognition technology according to a face picture (having the same function as the target portrait picture) uploaded by a player. The extracted key part is matched with a plurality of parts in the art image workable-material library, and one or more results with highest similarity (having the same function as the similarity exceeding the preset threshold) are provided to the player. 
     In one embodiment, by determining a part, similarity between which and the first part exceeds a preset threshold, in the feature image library as the target part, the accuracy of determining the target part is improved. 
     In S 208 , the target feature parameter, which matches the first part feature, of the target part feature is determined in the value range of the target part feature of the target part pre-recorded in the feature image library. 
     The feature image library may include a plurality of types (having the same function as the target part), for example, an eye type, a nose type, and a mouth type. Each of the different types may further include one or more features, and each feature corresponds to a value range. For example, the eye type includes three features A 1 , A 2 , and A 3  (having the same function as the target part feature). The feature A 1  corresponds to a value range a 1 , the feature A 2  corresponds to a value range a 2 , and the feature A 3  corresponds to a value range a 3 . For the nose type and the mouth type, reference may be made to the eye type, and details are not described herein again. 
     After the target part matching the first picture region is obtained, according to the value range of the target part feature of the target part pre-recorded in the feature image library, the target feature parameter matching the first part feature is determined in the value range. That is, the target feature parameter may be a value within the value range of the target part feature. 
     In an embodiment, the determining, in a value range of a target part feature of the target part pre-recorded in the feature image library, a target feature parameter, which matches the first part feature, of the target part feature may include: determining, in a case that a plurality of feature values matching a feature value of the first part feature are found in the value range, a maximum value in the plurality of feature values as the target feature parameter. 
     In an embodiment, in a case that there are a plurality of feature values of the target part feature that match the feature value of the first part feature, a maximum value of the plurality of feature values is determined as the target feature parameter. The foregoing description is merely an example, and is not limited herein. 
     In one embodiment, by determining the maximum value in the plurality of feature values matching the feature value of the first part feature as the target feature parameter, the accuracy of determining the target feature parameter is improved. 
     In an embodiment, the determining, in a value range of a target part feature of the target part pre-recorded in the feature image library, a target feature parameter, which matches the first part feature, of the target part feature may include: determining, in a case that no feature value matching a feature value of the first part feature is found in the value range, a preset default value in the value range as the target feature parameter. 
     In an embodiment, in a case that there is no feature value of the target part feature matching the feature value of the first part feature, the default value (for example, a default game character appearance) is determined as the target feature parameter. The foregoing description is merely an example, and is not limited herein. 
     In one embodiment, in a case that no feature value matching the feature value of the first part feature is found in the value range, the preset default value in the value range is determined as the target feature parameter, to save time and time costs. 
     In an embodiment, the determining, in a value range of a target part feature of the target part pre-recorded in the feature image library, a target feature parameter, which matches the first part feature, of the target part feature may include: determining, in a case that the target part feature includes a plurality of part features, a feature value of each part feature in value ranges of the plurality of part features pre-recorded in the feature image library, the target feature parameter including the feature value of the each part feature. 
     In an embodiment, in a case that the target part includes a plurality of part features, the feature value of the each part feature of the plurality of part features needs to be determined, the target feature parameter including the feature value of the each part feature. 
     For example, the target part is a nose part, and the nose part includes three features: nasal wings, a nasal tip, and a nasal bridge. Value ranges of the three features: the nasal wings, the nasal tip, and the nasal bridge, need to be determined. The foregoing description is merely an example, and is not limited in one embodiment of the present disclosure. 
     In one embodiment, in a case that the target part includes a plurality of part features, a value range of the each part feature of the plurality of part features may be determined, to improve the accuracy of determining the target feature parameter. 
     In S 210 , the target part is generated in the target game application according to the target feature parameter. 
     In an embodiment, in the target game application, the target part is generated according to the target feature parameter. For example, if the target feature parameter corresponds to one feature, the feature being eyes, a corresponding eyes part is generated according to a feature parameter of the eyes. Alternatively, if the target feature parameter corresponds to a plurality of features, the plurality of features being nasal wings, a nasal tip, and a nasal bridge, a corresponding nasal wings part, a corresponding nasal tip part, and a corresponding nasal bridge part are generated according to feature parameters corresponding to the nasal wings, the nasal tip, and the nasal bridge. The foregoing description is merely an example, and is not limited herein. 
     In an embodiment, after the target part is generated in the target game application according to the target feature parameter, the method may further include: encapsulating and combining, in a case that the target part includes a plurality of parts and the plurality of parts are all parts that are required for generating the target virtual operating object, the plurality of parts to obtain the target virtual operating object. 
     Specifically, in a case that the target part includes a plurality of parts and the plurality of parts included in the target part form all parts that are required for generating the target virtual operating object, the plurality of parts included in the target part may be encapsulated and combined to generate the target virtual operating object. 
     For example, in a game scene, parts of a game character appearance may include a face, a body, and four limbs. Using the face as an example for description, if the target part includes the face and the face includes sub-parts such as a forehead, eyebrows, an entire nose, nasal wings, a nasal tip, a nasal bridge, a  glabella , an entire mouth, mouth corners, two sides of a lower lip, the middle of the lower lip, two sides of an upper lip, the middle of the upper lip, entire eyes, lower eyelids, outer eye corners, eyelids, eye corners, a chin, a jaw, cheek bones, a hair style, a skin color, facial accessories, and entire ears. Such sub-parts are encapsulated and combined to form the face. In the same way, sub-parts of the body included in the target part are encapsulated and combined to form the body, and sub-parts of the four limbs included in the target part are encapsulated and combined to form the four limbs. The face, the body, and the four limbs are then encapsulated and combined to generate the game character appearance (having the same function as the target virtual operating object). 
     In an embodiment, the method further includes: encapsulating and combining the generated target part and a collaborative part to obtain the target virtual operating object in a case that the target part is a partial part used for generating the target virtual operating object. 
     The partial part indicates that the target part is some parts among all parts that are required for generating the target virtual operating object. That is, the target part cannot generate the target virtual operating object independently, but needs to be combined with another part (that is, the collaborative part) to generate the target virtual operating object jointly. It can be understood that the partial part may be one part or a plurality of parts. That is, the target part may be one part or a plurality of parts. The term “plurality of” means at least two. 
     The collaborative part is a part used for forming the target virtual operating object together with the target part. In an embodiment, the collaborative part may be a part at a default position in the target application, or a part generated according to a feature parameter inputted by a target account. 
     In an embodiment, if the target part includes a plurality of parts, but the plurality of parts cannot form all parts that are required for generating the target virtual operating object, the plurality of parts and the collaborative part other than the plurality of parts are encapsulated and combined to generate the target virtual operating object. The collaborative part is a necessary part for generating the target virtual operating object other than the plurality of parts. The collaborative part may be set as a default part in the target game application, or the collaborative part may be set through a manual input of a user corresponding to the target account. 
     For example, in a game scene, parts of a game character appearance may include a face, a body, and four limbs. When the target part includes the face only, sub-parts of the face are encapsulated and combined first, and the body and the four limbs are set as default parts in a game system, or the body and the four limbs are set by the user, and finally, the face, the body, and the four limbs are encapsulated and combined to generate the game character appearance (having the same function as the target virtual operating object). The foregoing description is merely an example, and is not limited herein. 
     In one embodiment, in a case that the target part includes a plurality of parts, the plurality of parts are encapsulated and combined in different manners described above, to generate the target virtual operating object, thereby improving the diversity of setting manners of the target virtual operating object, and improving the gaming experience of a user. 
     In an embodiment, after the target part is generated in the target game application according to the target feature parameter, the method may further include: encapsulating and combining, in a case that the target part includes one part and the one part and a collaborative part different from the one part jointly form all parts that are required for generating the target virtual operating object, the one generated part (that is, the target part) and the collaborative part to obtain the target virtual operating object, the collaborative part being a part at a default position in the target game application, or a part generated according to a feature parameter inputted by a target account. 
     In an embodiment, when the target part includes only one part, the one part and the collaborative part (any necessary part other than the one part for forming the target virtual operating object) are encapsulated and combined together to form the target virtual operating object. The collaborative part may be set as a default part in the target game application, or the collaborative part may be set through a manual input of a user corresponding to the target account. The foregoing description is merely an example, and is not limited herein. 
     In one embodiment, in a case that the target part includes one part, by encapsulating and combining the one part and the collaborative part to generate the target virtual operating object, the target virtual operating object can be set effectively, improving the gaming experience of the user. 
     A method for determining a game character appearance is described in the following with reference to  FIG. 4 . As shown in  FIG. 4 , the method may include the followings. 
     S 1 : A player uploads picture material (e.g., workable-picture). 
     When the player uploads the picture material (for example, a face picture), a server or a terminal device may check the specifications of the picture material uploaded by the player and checks whether value ranges of the specifications of the picture material conform to basic criteria. If not, it is necessary to inform the player to upload picture material again. For example, the user may be informed, through a text, speech, or picture, to upload the picture material again. The foregoing description is merely an example, and is not limited herein. 
     S 2 : Perform image processing on the picture material. 
     Edge detection and image pre-processing are performed on the obtained picture material to mark a feature image in the picture material image as a configurable region. A difference operation is then performed on the feature image to obtain a depth map after the difference operation, a closing operation is performed next on the depth map and a feature region of the depth map after the closing operation is split, and a contour value of the feature region is marked for the feature region to obtain contour information of the picture material (for example, the face picture). 
     S 3 : Match a public feature image library with a game character model library, and determine part information. 
     The public feature image library stores features of face pictures, and the game character model library stores features of game characters. The contour information of the face picture is matched with features of models in the game character model library one by one, to determine part information corresponding to the face picture. The foregoing description is merely an example, and is not limited herein. 
     S 4 : Synchronize the part information of the face picture into the character model library for retrieval. 
     The part information of the face picture is retrieved in the character model library to improve a matching degree between the part information of the face picture and features in the character model library. 
     S 5 : Synchronize, at the same time, a contour value marked after operation into the character model library for determining and matching processing. 
     The contour information of the face picture is matched with features of models in the game character model library. If a matching degree between the contour information of the face picture and a feature of a model in the game character model library exceeds a matching rate (for example, 0.5), the match succeeds. 
     A sequence of processing steps S 4  and S 5  is not limited. For example, S 4  and S 5  can be processed simultaneously. 
     S 6 : Retrieve a maximum result value preferably from the model library if there are results determined in a matching value range, or retrieve a default value from the model library if there is no result determined in the matching value range. 
     When a plurality of values are obtained after the matching between the face picture and the features in the character model library, a maximum value is selected as the matching result, or if the matching result cannot be obtained in the matching range, a default value is selected as the matching result. 
     A method for determining a game character appearance through facial recognition is described in the following with reference to  FIG. 5 . 
     As shown in  FIG. 5 , in the related art, a game player may manually set a game character appearance. An example of adjusting a face appearance is used. The game player can adjust a face appearance of a game character to be an appearance that the player is interested in through options shown on a game interface. However, for manual adjustment of contours, model quantity, and color quantity of character models, the infeasibility of manually presetting a massive number of model options on an interface, a complex interaction manner and complex naming raise the bar for a game player to enter a game. 
     In an embodiment, to resolve the foregoing problem, a method for determining a game character appearance through facial recognition is provided. As shown in  FIG. 6 , a game player may enter creation based on facial recognition by selecting an option on a game interface. Through the function of creation based on facial recognition, after the player uploads a picture, for example, a face picture that is photographed by a mobile device or selected from a picture gallery, the face is aligned with a preset mode according to coordinates of facial key points. Then, features of the face picture of the player are calculated. Next, the features of the face picture are matched with corresponding information coordinates in a character model feature database (having the same function as the feature image library), and are further matched with features in the character model feature database. Result information for each feature of the face picture is obtained from the character model feature database through matching. 
     In an embodiment, to resolve the foregoing problem, another method for determining a game character appearance through facial recognition is provided. As shown in  FIG. 7 , a game player may create a game character appearance by using a fixed setting and/or manual adjustment in combination with a manner of creation based on facial recognition. For example, most players chasing for individuality, after creating a game character appearance in a conventional creation manner, may further select dressing-up based on real-person recognition in some game scenes where social interaction is needed. The player uploads information about facial material and modifies the face and head portrait of a game character through facial recognition. Therefore, the character appearance of the game player can be quickly modified. 
     In an embodiment, to resolve the foregoing problem, still another method for determining a game character appearance through facial recognition is provided. As shown in  FIG. 8 , a game player may start a facial recognition dressing-up function according to a prop or a task in a game, to further change a game character appearance of the player. 
     In the manner of creation based on facial recognition, a gender, a virtual contour, a model, and a color can be quickly and easily selected for a game player according to body information and facial information in a face picture. In the manner of creating a game character appearance through the function of creation based on facial recognition, the problem of homogenization of game character appearances is effectively resolved, and the degree of complexity of manual operation and setting by a game player. 
     In one embodiment, the manner of creation based on facial recognition satisfies an ordinary player, a professional player, or a player chasing for individuality in game design, increases the length of the life cycle of a game product and improves the playability of the game product, and further simplifies edition iteration of individualized skins. In addition, the highly flexible customization of a game character appearance not only brings more interesting and individualized experience to the game, but also reduces the operating difficulty of a player.
