ABSTRACT:
A logo processing method includes: within a plurality of video frames sequentially received from a video source, comparing a base frame with at least a portion of the other video frames to generate a mask having at least one candidate region probably corresponding to at least one logo; performing post processing on the mask to correct the candidate region(s); and selecting at least one of the candidate region(s) as logo region(s) for indicating the logo(s).
