s101: and acquiring a video to be processed, wherein the video to be processed comprises a plurality of video frames.
Specifically, the video to be processed may be captured by a device (e.g., a mobile phone, a camera, a tablet, etc.) having a function of capturing video. The essence of the video to be processed is that it is made up of individual still pictures, which are referred to as video frames. Since the frequency of human eye recognition is limited, when the number of video frames seen in a unit time exceeds a certain number (for example, 25 video frames appear in 1 second), the picture is perceived as moving by human eyes.
S102: at least one specific video frame is extracted from a plurality of video frames in a video to be processed.
Specifically, the number of the specific video frames may be one, two, three, etc., which is not limited in this application, and the at least one specific video frame appears in the video to be processed at different times.
In an embodiment, the method for extracting the specific video frame may be to play the video to be processed according to a slow speed, a normal speed, a fast speed, or the like, and when the video frame deemed by the user to be needed is played, the user may pause the playing and copy the video frame corresponding to the currently paused page, thereby obtaining the specific video frame.

S302: and obtaining the area corresponding to the target from the gray-scale image.
Specifically, in one embodiment, the region corresponding to the target may be manually selected from the grayscale image; in another embodiment, the number of the selected specific video frames is at least two, and due to different object forms (e.g., postures, positions, etc.), the object in each specific video frame is different from the object in another specific video frame in form, and the area corresponding to the object in the specific video frame can be obtained by simple superposition.
S303: and extracting the target from the color image according to the region corresponding to the target.
In other embodiments, the method for extracting the object in the specific video frame in step S201 may be other methods, and the present application is not limited thereto, and for example, the color image of the specific video frame may be converted into a grayscale image, the object may be extracted from the grayscale image, and the extracted object may be converted from the grayscale image into the color image.
