Abstract
A method and system for image and video encoding and decoding is disclosed. A plurality of macro-blocks of pixels are defined in the image to be encoded, for subsequent block-by-block encoding and decoding. A node-cell structure of pixels is individually defined for each macro-block. The node pixels are encoded first. Then, the cell pixels are encoded using the decoded node pixels as a reference. This allows increasing macro-block size without a significant degradation of pixel encoding quality.
