Abstract
A method and apparatus for performing multiple frame image compression and decompression of motion video data are provided. In one embodiment, a plurality of sequential frames in a motion video sequence are collected and digitally filtered as a single image. At least some of the results of the digital filtering are then encoded to generate compressed data. In another embodiment, a plurality of sequential frames are filtered as if the boundary of each frame is adjacent to a boundary in the same spatial location of another of the plurality of sequential frames.
