ABSTRACT:
An adaptive method for television image encoding by splitting the video image to be transmitted into sub-bands at the time of analysis filtering of the image encoder. These sub-bands are split into a tree-like structure by filtering and decimation. Local adaptive filtering is carried out in the analysis filters of each sub-band.
