Abstract:
Disclosed are a video foreground target extraction method and apparatus. In the method, firstly, a transparency estimation value is recalculated by measuring the reliability of foreground and background pixel pairs to obtain a first transparency mask of the first image; then, a new picture is generated by superposing grayscale information and a second transparency mask of the first image is obtained, and the first transparency mask of the first image is further modified, finally, the foreground object of a certain frame of image in a video is extracted by using the modified first transparency mask. The present disclosure can comprehensively use the reliability and grayscale information of the foreground and background pixel pairs in a certain frame of image in the video, and provides a new video foreground target extraction solution.
