Abstract

A video stream is processed in a manner which may facilitate compression. Where a video image stream has adjacent fields which may represent different video images, interpolated fields may be generated. This can improve motion mask generation. Proximate motion indicating regions of a motion mask may be coalesced in an effort to reduce noise. After separation of background and foreground images from the video images of the stream, weighted averaging may be applied to non-motion indicating regions of the background images in an effort to reduce noise. A blending mask having boundaries which taper outwardly from motion indicating regions to non-motion indicating regions may be used to combine the foreground and background images. Output video images may be selected based on an extent and/or rate of motion of regions of the input video images.
