Image and Video Compression Techniques    

The technology relates to techniques and apparatus for compressing images.

Overview

It proposes that in a coding technique in which an image is partitioned into blocks which are pre-processed and then subject to zero tree coding to produce output data, if the pre-processed data met certain criteria, the coding of the pre-processed data should be changed appropriately.

The “symbol concatenation” and “bit stuffing” used in the analysis are particularly advantageous in the case that the pre-processed data contains a high proportion of zeros, therefore this invention is suitable for video compression.

Primary Application of the Technology

The compression technique is useful in video compression
