A method of image processing, includes: receiving at least one video frame of a video sequence, the at least one video frame including at least one foreground subject and a background; and processing the at least one video frame so as to separate the at least one foreground subject from the background. The processing includes: obtaining a reference image including the background; comparing the at least one video frame to the reference image; and generating a pixel mask as a result of the comparison, the pixel mask indicating whether a pixel of the at least one video frame belongs to the foreground subject or to the background. The method further comprises at least partially determining edges of the at least one foreground subject in the at least one video frame, and modifying the pixel mask based on the determined foreground subject edges. |
