FIG. 1 is a schematic diagram of an application environment according to an embodiment of the present application. Referring to FIG. 1, a computer device 1 is connected to a live streamer terminal 2, and may receive and obtain streaming video data sent by the live streamer terminal 2. In this embodiment, the computer device 1 is used as a user terminal, and may be an independent electronic device having a camera function, such as a mobile phone, a portable device, and a PC. The computer device may alternatively be an independent functional module that is attached to a main electronic device having a camera function and then helps the main electronic device to implement the function of interaction during live video.
FIG. 2 is a schematic flowchart of an embodiment of an interaction method for live video according to the present application. It can be understood that the flow chart in this method embodiment is not used to limit the order of execution of the steps. An exemplary description is made below by taking a computer device as an execution subject.
As shown in FIG. 2, the method of interaction for live video may include steps S200 to S208.
In step S200, a streaming video of a live streamer and an image of a user captured in real time by a user terminal are obtained.
Specifically, the computer device 1 is connected to the live streamer terminal 2 through a network, and then may obtain a streaming video sent by the live streamer terminal 2. The streaming video is video data captured by the live streamer using the live streamer terminal 2 during live streaming. Certainly, as a terminal device of a user, the computer device 1 is provided with a camera unit for capturing an image of a user of a user. In other words, the computer device 1 can obtain the streaming video of the live streamer and an image of a user of a user.
In step S202, the streaming video and the image of the user are displayed in the same video play box.
Specifically, the computer device 1 further provides a display interface on which a video play box is provided for playing video data. In this embodiment, the video play box includes a first part and a second part, the first part being used for presenting the streaming video and the second part being used for presenting the image of the user, such that the obtained streaming video and the image of the user are played in the video play box.
It should be noted that in this embodiment, the computer device 1 plays the streaming video and the image of the user in the first part and the second part, for example, an upper part and a lower part or a left part and a right part, of the video play box in a seamless stitching manner. For example, the computer device 1 may set the first part and the second part as being in an upper-lower stitching mode when the streaming video is in a landscape mode, or may set the first part and the second part as being in a left-right stitching mode when the streaming video is in a portrait mode. Certainly, in other embodiments, both the streaming video and the image of the user are played in the video play box in other manners. For example, the streaming video and the image of the user are played with the two separated in the video play box, or with the two contained together therein in the form of large and small playback windows, which is not limited herein. In this embodiment, the streaming video and the image of the user are played in a stitching manner, such that videos of a live streamer and a user can be displayed within a same box. As such, the user may feel being close to the live streamer.
In step S204, a first gesture of a user in the image of the user is obtained and recognized, and the first gesture is compared with a second gesture in a preset table for correspondence between gestures and special effects.
In step S206, when the first gesture matches with the second gesture, a first video special effect corresponding to the second gesture is obtained by querying the table for correspondence between gestures and special effects.
In step S208, the first video special effect is displayed in the video play box.
Specifically, after displaying the image of the user and the streaming video in the video play box, the computer device 1 recognizes each frame from the image of the user by means of image recognition so as to obtain an image of a palm in each frame from the image of the user, and then recognizes a gesture. In this embodiment, the computer device 1 may pre-store a gesture recognition model that can recognize gestures, and then obtain an image in video data of the image of the user for recognition. When recognizing the first gesture in the image of the user, the computer device compares the first gesture with the second gesture in the preset table for correspondence between gestures and special effects. The table for correspondence between gestures and special effects includes a one-to-one correspondence between gestures and video special effects.
When the first gesture recognized by the computer device 1 matches with the second gesture in the table for correspondence between gestures and special effects, the computer device further finds out the first video special effect corresponding to the second gesture by querying the table for correspondence between gestures and special effects. Finally, the computer device 1 displays the first video special effect in the video play box.
As shown in FIG. 3, in an exemplary embodiment, the process of displaying the first video special effect in the video play box in step S208 includes steps S300 to S302.
In step S300, a first palm position of the first gesture, and a first face position of the face of the live streamer in the streaming video are obtained.
In step S302, the video special effect is displayed extendingly with a start point at the first palm position and an end point at the first face position.
Specifically, after finding out, through querying, the first video special effect corresponding to the second gesture, the computer device 1 displays the video special effect in the image of the user and the streaming video. The computer device 1 first obtains a first position of a palm of the user that makes the first gesture in the image of the user, and then obtains the first face position of the live streamer in the streaming video. In this embodiment, because there is a relatively fixed relationship between positions of the image of the user and the streaming video in the video play box (that is, the positions remain unchanged within a short period of time), an image of the palm of the first gesture in an image of a user frame of the image of the user and a face image of the live streamer in a streaming video frame of the streaming video can be recognized by using a human body recognition model.
Then, the computer device 1 marks the first palm position based on relative position coordinates of the palm image in the frame of the image of the user; and the computer device marks the first face position based on relative position coordinates of the face image in the streaming video frame, where the relative position coordinates indicate the position of the palm image in the frame of the image of the user or the position of the face image in the streaming video frame. Finally, the computer device 1 displays the video special effect extendingly with the first palm position as the start point and the first face position as the end point. Referring to FIG. 4, a user gives a gesture of “heart”, and then a video special effect brings in a series of hearts extending from an image of a user to a streaming video. In this way, the computer device 1 displays the video special effect in the image of the user and the streaming video in the form of “interaction”, thereby enhancing interaction during live video.
As shown in FIG. 5, in an exemplary embodiment, the process of displaying the first video special effect in the video play box in step S208 further includes steps S400 to S404, in addition to steps S300 to S302.
In step S400, it is monitored whether a palm of the first gesture has moved.
In step S402, if the palm of the first gesture has moved, a second palm position of the moved palm of the first gesture is obtained.
In step S404, the start point of the video special effect is changed from the first palm position to the second palm position.
In this embodiment, in the process of the computer device 1 displaying the video special effect extendingly with the first palm position as the start point and the first face position as the end point, the computer device also continues to monitor whether the palm of the first gesture has moved. If the palm of the first gesture has moved, the computer device obtains a second palm position of the palm after movement, and then changes the start point of the video special effect from the first palm position to the second palm position.
As shown in FIG. 6, in another exemplary embodiment, the process of displaying the first video special effect in the video play box in step S208 further includes steps S500 to S504, in addition to steps S300 to S302.
In step S500, it is monitored whether the face of the live streamer has moved.
In step S502, if the face of the live streamer has moved, a second face position of the moved face of the live streamer is obtained.
In step S504, the end point of the video special effect is changed from the first face position to the second face position.
In this embodiment, in the process of the computer device 1 displaying the video special effect extendingly with the first palm position as the start point and the first face position as the end point, the computer device also continues to monitor whether the face of the live streamer has moved. If the face of the live streamer has moved, a second face position of the face after movement is obtained, and the start point of the video special effect is then changed from the first face position to the second face position.
The start point and the end point of the video special effect are adjusted by monitoring the palm position of the first gesture and the face position of the live streamer, so that the “targeted” extension of the video special effect in interaction during live video can be improved, thereby enhancing the interactive effect.
As shown in FIG. 7, in an exemplary embodiment, the process of displaying the first video special effect in the video play box in step S208 includes steps S600 to S602.
In step S600, a face image of the live streamer in the streaming video is obtained.
In step S602, the face image and a facial special effect corresponding to the first gesture are synthesized and then displayed, where the facial special effect includes at least one of a clothing special effect and an expression special effect.
In this embodiment, the computer device 1 recognizes the first gesture and determines that the first gesture matches with the second gesture in the table for correspondence between gestures and special effects, and thus triggers a video special effect corresponding to the first gesture. The video special effect involves synthesizing a preset facial special effect and a face image of the current live streamer in the streaming video and then displaying the same. The facial special effect includes a clothing special effect or an expression special effect. For example, FIG. 8 shows a usual live streaming interface, and FIG. 9 shows a live streaming interface after the use of a facial special effect. As shown in FIG. 9, a first gesture for coin giving is generated in the lower image for the user, and the first gesture for coin giving can trigger a facial special effect of adding sunglasses onto the current face image of a live streamer. Therefore, the computer device 1 displays, in the upper streaming video, a face image of the live streamer with the facial special effect added. The triggering of the video special effect in the face image of the live streamer by a user can also well enhance the interactive effect.
As shown in FIG. 10, in an exemplary embodiment, the method for playing live video further includes steps S700 to S702, in addition to steps S200 to S208 described above.
In step S700, a gesture duration of the first gesture is counted.
In step S702, a second video special effect is triggered when the gesture duration is greater than or equal to a preset duration threshold.
Specifically, after the computer device 1 displays the video special effect in the video play box, the computer device also continues to monitor the gesture duration of the first gesture. The second video special effect is triggered when the gesture duration is greater than or equal to a preset threshold. Certainly, the second video special effect may alternatively be a further enhancement of the video special effect, such as a change in the color and shape. In this way, the interactive effect during live video is further enhanced.
It can be learned from above that by means of the method of interaction for live video provided in this embodiment, a streaming video of a live streamer and an image of a user captured in real time by a user terminal can be obtained and displayed in the same video play box; then a first gesture of a user in the image of the user are obtained and recognized, and the first gesture is compared with a second gesture in a preset table for correspondence between gestures and special effects; and when the first gesture matches with the second gesture, a video special effect corresponding to the second gesture is obtained by querying the table for correspondence between gestures and special effects, and the video special effect is then displayed in the video play box. By means of the above operations, images for a live streamer and a user can be presented in the same interface, and the interaction between a user and a live streamer can be linked using video special effects, which enriches the way of interaction presentation, and strengthens the sense of participation in interaction.
In addition, the present application further provides a computer device. FIG. 11 is a schematic diagram of an optional hardware architecture of a computer device according to the present application.
In this embodiment, the computer device 1 may include, but is not limited to, a storage 11, a processor 12, and a network interface 13 that can be communicatively connected to each other via a system bus. The computer device 1 is connected to a network (not shown in FIG. 11) through the network interface 13, and is connected to a live streamer terminal, etc. (not shown in FIG. 11) through the network to perform data exchange. The network may be a wireless or wired network such as Intranet, Internet, a global system of mobile communication (GSM), wideband code division multiple access (WCDMA), a 4G network, a 5G network, Bluetooth, Wi-Fi, or a telephone network.
It should be noted that FIG. 11 shows only the computer device 1 having components 11 to 13, but it should be understood that not all of the illustrated components are required to be implemented, and more or fewer components may be implemented instead.
The storage 11 includes at least one type of readable storage medium, and the readable storage medium includes a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., an SD or DX memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disc, etc. In some embodiments, the storage 11 may be an internal storage unit of the computer device 1, for example, a hard disk or a memory of the computer device 1. In some other embodiments, the storage 11 may alternatively be an external storage device of the computer device 1, for example, a plug-in hard disk disposed on the computer device 1, a smart media card (SMC), a secure digital (SD) card, a flash card, etc. Certainly, the storage 11 may alternatively include both the internal storage unit of the computer device 1 and the external storage device thereof. In this embodiment, the storage 11 is generally used to store an operating system and various types of application software installed in the computer device 1, such as program code of a baffle application and program code of an apparatus 200 of interaction for live video. In addition, the storage 11 may be further used to temporarily store various types of data that has been output or will be output.
The processor 12 may be, in some embodiments, a central processing unit (CPU), a controller, a microcontroller, a microprocessor, or other data processing chips.

When the apparatus 200 of interaction for live video is run, the computer device can obtain a streaming video of a live streamer and an image of a user captured in real time by a user terminal, and display the streaming video and the image of the user in a same video play box; then the computer device obtains and recognizes a first gesture of a user in the image of the user, and compares the first gesture with a second gesture motion in a preset table for correspondence between gestures and special effects; and the computer device finds out, when the first gesture matches with the second gesture, a video special effect corresponding to the second gesture obtained by querying the table for correspondence between gestures and special effects is displayed in the video play box. By means of the above operations, images for a live streamer and a user can be presented in the same interface, and the interaction between a user and a live streamer can be linked using video special effects, which enriches the way of interaction presentation, and strengthens the sense of participation in interaction.
Heretofore, the hardware structure and functions of the computer device of the present application have been described in detail. Embodiments of the present application are provided below based on the computer device described above.
FIG. 12 is a diagram of program modules in an embodiment of an apparatus 200 of interaction for live video according to the present application.
In this embodiment, the apparatus 200 of interaction for live video includes a series of computer-readable instructions stored in the storage 11, and when the computer-readable instructions are executed by the processor 12, an interactive function during live video in this embodiment of the present application can be implemented. In some embodiments, the apparatus 200 of interaction for live video may be divided into one or more modules on the basis of specific operations implemented by various parts of the computer-readable instructions. For example, in FIG. 12, the apparatus 200 of interaction for live video may be divided into an obtaining module 201, a display module 202, a recognition module 203, a determination module 204, a query module 205, and a monitoring module 206. In the modules:
the obtaining module 201 is to obtain a streaming video of a live streamer and an image of a user captured in real time by a user terminal.
Specifically, the computer device is connected to the live streamer terminal through a network, and then may obtain a streaming video sent by the live streamer terminal. The streaming video is video data captured by the live streamer using the live streamer terminal during live streaming. Certainly, as a terminal device of a user, the computer device is provided with a camera unit for capturing an image of a user of a user. Therefore, the obtaining module 201 can obtain the streaming video of the live streamer and the image of the user.
The display module 202 is to display the streaming video and the image of the user in a same video play box.
Specifically, the computer device further provides a display interface on which a video play box is provided for playing video data. In this embodiment, the video play box includes a first part and a second part, the first part used for presenting the streaming video and the second part used for presenting the image of the user, such that the display module 202 can play the obtained streaming video and image for the user in the video play box.
It should be noted that in this embodiment, the display module 202 plays the streaming video and the image of the user in the first part and the second part, for example, an upper part and a lower part or a left part and a right part, of the video play box in a seamless stitching manner. For example, the computer device 1 may set the first part and the second part as being in an upper-lower stitching mode when the streaming video is in a landscape mode, or may set the first part and the second part as being in a left-right stitching mode when the streaming video is in a portrait mode. Certainly, in other embodiments, the display module 202 may alternatively play both the streaming video and the image of the user in the video play box in other manners. For example, the streaming video and the image of the user are played with the two separated in the video play box, or with the two contained together therein in the form of large and small playback windows, which is not limited here. In this embodiment, the streaming video and the image of the user are played in a stitching manner, such that videos of a live streamer and a user can be displayed within a same box. As such, the user may feel being close to the live streamer.
The recognition module 203 is to obtain and recognize a first gesture of a user in the image of the user.
The determination module 204 is to compare the first gesture with a second gesture in a preset table for correspondence between gestures and special effects so as to determine whether the two matches with each other.
The query module 205 is to obtain, if the first gesture matches with the second gesture, a video special effect corresponding to the second gesture by querying the table for correspondence between gestures and special effects.
The display module 202 is further to display the video special effect in the video play box.
Specifically, after the display module 202 displays the image of the user and the streaming video in the video play box, the recognition module 203 recognizes each frame from the image of the user by means of image recognition so as to obtain an image of a palm in each frame from the image of the user and then recognizes a gesture. In this embodiment, the computer device may pre-store a gesture recognition model that can recognize gestures, and then the recognition module 203 may invoke the gesture recognition model to recognize an image in obtained video data of the image of the user. When the recognition module 203 recognizes the first gesture in the image of the user, the determination module 204 compares the first gesture with the second gesture in the preset table for correspondence between gestures and special effects to determine whether the two matches with each other. The table for correspondence between gestures and special effects includes a one-to-one correspondence between gestures and video special effects.
When the determination module 204 determines that the first gesture matches with the second gesture in the table for correspondence between gestures and special effects, the query module 205 further finds out the first video special effect corresponding to the second gesture by querying the table for correspondence between gestures and special effects. Finally, the display module 202 displays the first video special effect in the video play box.
In this embodiment, the process of the display module 202 displaying the first video special effect in the video play box includes: obtaining a first palm position of the first gesture, and a first face position of the face of the live streamer in the streaming video; and displaying the video special effect extendingly with a start point at the first palm position and an end point at the first face position.
Specifically, the display module 202 first obtains a first position of a palm of the user that makes the first gesture in the image of the user, and then obtains the first face position of the live streamer in the streaming video. In this embodiment, because there is a relatively fixed relationship between positions of the image of the user and of the streaming video in the video play box (that is, the positions remain unchanged within a short period of time), an image of the palm making the first gesture in a frame from the image of the user and a face image of the live streamer in a streaming video frame of the streaming video can be recognized by using a human body recognition model.
Then, the display module 202 marks the first palm position based on relative position coordinates of the palm image in the frame of the image of the user; and the display module marks the first face position based on relative position coordinates of the face image in the streaming video frame, where the relative position coordinates indicate the position of the palm image in the frame of the image of the user or the position of the face image in the streaming video frame. Finally, the display module 202 displays the video special effect extendingly with the first palm position as the start point and the first face position as the end point. Referring to FIG. 4, a user gives a gesture of “heart”, and then a video special effect brings in a series of hearts extending from an image of a user to a streaming video. In this way, the computer device 1 displays the video special effect in the image of the user and the streaming video in the form of “interaction”, thereby enhancing interaction during live video.
The monitoring module 206 is to monitor whether a palm of the first gesture has moved in the process of the display module 202 displaying the first video special effect in the video play box.
The display module 202 is further to obtain, if the palm of the first gesture has moved, a second palm position of the moved palm of the first gesture, and to change the start point of the video special effect from the first palm position to the second palm position.
The monitoring module 206 is further to monitor whether the face of the live streamer has moved in the process of the display module 202 displaying the first video special effect in the video play box.
The display module 202 is further to obtain, if the face of the live streamer has moved, a second face position of the moved face of the live streamer, obtain a second palm position of the moved palm of the first gesture, and to change the end point of the video special effect from the first face position to the second face position.
The start point and the end point of the video special effect are adjusted by monitoring the palm position of the first gesture and the face position of the live streamer, so that the “targeted” extension of the video special effect in interaction during live video can be improved, thereby enhancing the interactive effect.
In another embodiment, the display module 202 is further to obtain a face image of the live streamer in the streaming video, to synthesize the face image and a facial special effect corresponding to the first gesture and to display the same, where the facial special effect includes at least one of a clothing special effect and an expression special effect.
In this embodiment, presetting the video special effect by the computer device includes: synthesizing a preset facial special effect and a face image of the current live streamer in the streaming video and then displaying the same. The facial special effect includes a clothing special effect or an expression special effect. For example, FIG. 8 shows a usual live streaming interface, and FIG. 9 shows a live streaming interface after the use of a facial special effect. As shown in FIG. 9, a first gesture for coin giving is generated in the lower image for the user, and the first gesture for coin giving can trigger a facial special effect of adding sunglasses onto the current face image of a live streamer. Therefore, the display module 202 displays, in the upper streaming video, a face image of the live streamer with the facial special effect added. The triggering of the video special effect in the face image of the live streamer by a user can also well enhance the interactive effect.
Certainly, in another embodiment, the monitoring module 206 is further to count a gesture duration of the first gesture.
The display module 202 is further to trigger, if the gesture duration is greater than or equal to a preset duration threshold, a second video special effect.
Specifically, after the display module 202 displays the video special effect in the video play box, the monitoring module 206 continues to monitor the gesture duration of the first gesture. When the monitoring module 206 determines that the gesture duration is greater than or equal to a preset threshold, the display module 202 triggers the display of the second video special effect. Certainly, the second video special effect may alternatively be a further enhancement of the video special effect, such as a change in the color and shape. In this way, the interactive effect during live video is further enhanced.
It can be learned from above that the computer device can obtain a streaming video of a live streamer and an image of a user captured in real time by a user terminal, and display the streaming video and the image of the user in a same video play box; then the computer device obtains and recognizes a first gesture of a user in the image of the user, and compares the first gesture with a second gesture in a preset table for correspondence between gestures and special effects; and the computer device finds out, when the first gesture matches with the second gesture, a video special effect corresponding to the second gesture obtained by querying the table for correspondence between gestures and special effects is displayed in the video play box. By means of the above operations, images for a live streamer and a user can be presented in the same interface, and the interaction between a user and a live streamer can be linked using video special effects, which enriches the way of interaction presentation, and strengthens the sense of participation in interaction.
