Abstract

The present invention provides a method and apparatus for processing a video frame (201) in a video file, the method comprising: for each predetermined numerical value (i) of one or more predetermined numerical values, comparing the video frame (201) with a video frame (202) spaced prior to the video frame (201) by the predetermined numerical value (i) of frames to obtain a first inter-frame difference (204); comparing the video frame (201) with a video frame (203) spaced after the video frame (201) by the predetermined numerical value (i) of frames to obtain a second inter-frame difference (205); and for each pixel of the video frame (201), obtaining a confidence map (206) associating the video frame (201) by the predetermined numerical value based on a smaller value of the first inter-frame difference (204) and the second inter-frame difference (205); and determining, at least based on a value of each pixel in one or more of the confidence maps (206) associated with a corresponding predetermined numerical value, whether the pixel belongs to a foreground.
