Abstract: Systems and methods presented herein provide for video compression and decompression. In one embodiment, a video compression system includes a decimation filter operable to receive a video datastream, and to filter the video datastream to remove spatial data components and temporal data components of the video datastream. The system also includes a video codec operable to compress the filtered video datastream and a comparator operable to compare the video datastream to the filtered-compressed video datastream, and to determine a difference video datastream based on the comparison. The system also includes a generator operable to generate a tool for decompressing the filtered-compressed video datastream based on the difference video datastream.
