Abstract:

A novel rate control scheme is proposed dedicatedly for JPEG2000 image coding. By predicting bitrate of coded data and updating it adaptively, the proposed scheme can be executed in parallel with the code-block coding of code-block coding such as coefficient bit modeling and arithmetic coding. The proposed scheme successfully reduces computational cost and working memory size of the process down to 29% and 13%, respectively, comparing to a conventional approach in case of 1/16 compression, and hence is suitable to be used in embedded systems.
