     DETAILED DESCRIPTION 
     In order to better understand the above purposes, features and advantages of the present disclosure, the solution of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments may be combined with each other without conflict. 
     Many specific details are described in the following description to facilitate full understanding of the disclosure, and the disclosure may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, not all of them. 
     In order to meet the user&#39;s requirements for displaying effects of pictures, the present disclosure provides a picture processing method. First, a target object segmentation picture and a background completion picture from a same original picture are determined as the pictures to be processed. Second, special effect processing is performed on the target object segmentation picture and the background completion picture separately, according to a picture type of the target object segmentation picture, to obtain a special effect picture corresponding to the target object segmentation picture and a special effect picture corresponding to the background completion picture. Finally, the respective special effect pictures corresponding to the target object segmentation picture and the background completion picture are synthesized to generate the rotating animation corresponding to the original picture. In the embodiments of the present disclosure, through the rotating animation, the original picture can be displayed to users in a stereoscopic and dynamic form, meeting the user&#39;s requirements for displaying effects of pictures. 
     On the basis of the above, the embodiment of the present disclosure provides a picture processing method. Referring to  FIG.  1   ,  FIG.  1    is a flowchart of a picture processing method according to an embodiment of the present disclosure. The method includes the following steps. 
     In step S 101 , pictures to be processed are obtained, and the pictures to be processed include a target object segmentation picture and a background completion picture from a same original picture. 
     In the embodiment of the present disclosure, after determining the original picture to be processed, the target object in the original picture is separated from the background to obtain the target picture segmentation picture and the background completion picture corresponding to the original picture. The target picture segmentation picture includes the target object in the original picture, and the background completion picture includes the background in the original picture. The target object may include portraits, animals, plants, etc. Usually, the original picture includes at least one target object. 
     Specifically, the target object is extracted from the original picture to obtain the target picture segmentation picture corresponding to the original picture. After the target object is extracted and removed from the original picture, the original picture is not complete now. Padding may be performed in the area where the target object is removed to obtain a complete picture as the background completion picture corresponding to the original picture. The padding may be performed in a way of understanding content of the original picture by using a conventional algorithm model and then padding based on the understood content. 
     In the embodiment of the present disclosure, after obtaining the target object segmentation picture and background completion picture from the same original picture, the target object segmentation picture and background completion picture are determined as the pictures to be processed. 
     In step S 102 , special effect processing is performed on the target object segmentation picture and the background completion picture separately, according to a picture type of the target object segmentation picture, to obtain a special effect picture corresponding to the target object segmentation picture and a special effect picture corresponding to the background completion picture. 
     In the embodiment of the present disclosure, before processing the picture, the picture type of the target object segmentation picture is first identified, and then special effect processing is performed on the target object segmentation picture and background completion picture separately with a special effect processing scheme corresponding to the picture type of the target object segmentation picture. 
     The picture type may include a full body picture and a half body picture. For the full body picture and the half body picture, the embodiments of the present disclosure provide different processing methods based on the characteristics of the full body picture and the half body picture. 
     For a portrait picture or an animal picture, one of the distinguishing features between the full body picture and the half body picture is that the full body picture usually contains a foot feature, while the half body picture do not contain the foot feature. Therefore, in the embodiment of the present disclosure, the picture type of the target object segmentation picture may be determined by identifying whether the target object segmentation picture contains the foot feature. Specifically, if the target object segmentation picture contains the foot feature, the target object segmentation picture is determined as the full body picture, otherwise it is determined as the half body picture. 
     In addition, the method for identifying the type of the target object segmentation picture is not limited herein. 
     In an embodiment of the present disclosure, the target object segmentation picture may include multiple target objects, such as a multi-person picture. Assuming that the multi-person picture includes not only a full body portrait, but also a half body portrait, in order to ensure the display effect of the original picture, the multi-person picture may be determined as the half body picture, and then it may be processed according to the special effect processing method for the half body picture. 
     Specifically, it is determined first whether the target object in the target object segmentation picture includes a half body object. If it is determined that the target object in the target object segmentation picture includes the half body object, the picture type of the target object segmentation picture is determined as the half body picture. Otherwise, the picture type of the target object segmentation picture is determined as the full body picture. 
     In addition, when the target objects are animals, plants, etc., the features of animals and plants may be learned through Big Data learning, and then the picture type of the target object segmentation picture may be determined based on the learned features, which will not be detailed in the embodiment of the present disclosure. 
     In the embodiment of the present disclosure, after determining the picture type of the target object segmentation picture, the special effect processing method for the target object segmentation picture and background completion picture is determined based on the picture type of the target object segmentation picture. After the corresponding special effect processing method is used to process the target object segmentation picture and background completion picture separately, the special effect pictures corresponding to the target object segmentation picture and background completion picture are obtained. 
     In an embodiment of the present disclosure, if it is determined that the target object segmentation picture belongs to the full body picture, the target object segmentation picture is translated and enlarged according to a preset first direction to obtain the special effect picture corresponding to the target object segmentation picture. The preset first direction is leftward or rightward. Then, a rotation of the perspective view of the background completion picture is implemented according to a preset second direction to obtain the special effect picture corresponding to the background completion picture. The preset second direction is leftward or rightward, and the preset first direction is different from the preset second direction. 
     That is, the target object segmentation picture may be translated and enlarged rightward, and the background completion picture may be rotated in perspective leftward. Alternatively, the target object segmentation picture may be translated and enlarged leftward, and the background completion picture may be rotated in perspective rightward. 
     In another embodiment of the present disclosure, if the target object segmentation picture belongs to the half body picture, the target object segmentation picture is enlarged according to a forward direction to obtain the special effect picture corresponding to the target object segmentation picture. Then, the perspective view of the background completion picture is rotated in an effect of a front leaning to a preset angle, to obtain the special effect picture corresponding to the background completion picture. The preset angle may include any angle from 45 degrees to 90 degrees. 
     In the above special effect processing method, both the background completion picture and the target object segmentation picture are subject to stereoscopic dynamic processing. Therefore, the present disclosure may meet the user&#39;s requirements for stereoscopic dynamic display of pictures. In addition, in the embodiment of the present disclosure, the target picture segmentation picture is enlarged, highlighting the target object in the original picture, which can improve the user experience to a certain extent. 
     In step S 103 , the special effect picture corresponding to the target object segmentation picture and the special effect picture corresponding to the background completion picture are synthesized to generate a special effect video corresponding to the original picture. 
     In the embodiment of the present disclosure, after performing special effect processing on the target object segmentation picture and the background completion picture separately, the special effect pictures corresponding to the target object segmentation picture and the background completion picture are obtained, and then the special effect pictures are synthesized to generate the special effect video corresponding to the original picture. Through the special effect video corresponding to the original picture, the target object in the original picture can be displayed in a stereoscopic and dynamic form, and the user experience can be improved. 
     In an embodiment of the present disclosure, the special effect pictures corresponding to the target object segmentation picture and the background completion picture may be synthesized to generate a rotating animation corresponding to the original picture. 
     In an embodiment of the present disclosure, in order to ensure the effect of picture processing, after synthesizing the special effect pictures corresponding to the target object segmentation picture belonging to the half body picture and the corresponding background completion picture, a connection point between the target object in the special effect picture corresponding to the target object segmentation picture and the special effect picture corresponding to the background completion picture is determined first. Then, based on the connection point, the special effect pictures corresponding to the target object segmentation picture and the background completion picture are synthesized to generate the rotating animation corresponding to the original picture, so that there is a connection point between the target object and the background completion picture in the synthesized rotating animation to ensure the display effects of pictures. 
     In the picture processing method according to the embodiments of the present disclosure, first, the target object segmentation picture and background completion picture from the same original picture are determined as the picture to be processed. Then, the picture type of the target object segmentation picture is identified, special effect processing is performed on the target object segmentation picture and the background completion picture separately on the basis of the picture type of the target object segmentation picture, to obtain a special effect picture corresponding to the target object segmentation picture and a special effect picture corresponding to the background completion picture. Finally, the special effect pictures corresponding to the target object segmentation picture and the background completion picture are synthesized to generate the rotating animation of the original picture. In the embodiments of the present disclosure, through the rotating animation, the original picture can be displayed to users in a stereoscopic and dynamic form, meeting the user&#39;s requirements for displaying effects of pictures. 
     In an application scenario, the original picture may include multiple portrait pictures. In the picture processing method according to the embodiment of the present disclosure, the corresponding special effect video may be obtained for each portrait picture, and then the special effect videos corresponding to multiple portrait pictures are composed into an album. 
     In practical applications, multiple pictures may be displayed at the same time in stereoscopic and dynamic form when playing the album, meeting the effect requirements of users to convert pictures into videos for stereoscopic and dynamic display, and improving the user experience.
