As a new still image compression standard,JPEG2000 has many advantages,such as higher compression rate and multi-resolution format.JPEG2000 coding is embedded block coding with optimized truncation (EBCOT),and the process of code adopts the MQ arithmetic coding.This paper analyzes the deficiency of MQ arithmetic coder in coding the image with single content and less information,and proposes an improved algorithm of the MQ arithmetic coder to improve the PSNR of coding the simple images and the quality of the decoded images.

Key words: JPEG2000;EBCOT;MQ arithmetic coding
