摘要 Additional data compression is achieved by enhancing the spatial and temporal correlation of the data in a pre-processing module prior to sending the data to an encoding algorithm, such as for example, the MPEG algorithm. An input frame of data is decomposed into a luminance frame and two chrominance frames. The luminance frame is transformed on the basis of each of a plurality of luminance pixels within the frame to produce a transformed luminance frame having a plurality of transformed luminance pixels. A map describing a relationship between the plurality of luminance pixels of the luminance frame and the plurality of transformed luminance pixels of the transformed luminance frame is created. The two chrominance frames are transformed according to the map to produce two transformed chrominance frames. The transformed luminance frame and the two transformed chrominance frames are integrated to produce a transformed output frame.
