JPEG2000 is the new standard for the compression of images, which succeeds to JPEG. It's has a much higher algorithmic complexity. The complexity of the entropy encoder ( EBCOT) is the most significant in JPEG2000. Which alone constitutes about 70% of the overall processing time for compression of an image. This new standard has many features and characteristics (region of interest, several types of decompression). In this paper we are interested on studying the algorithm of JPEG2000 and the most complex in the JPEG2000 compression process, the EBCOT entropy encoder, and its performance are presented.
