Abstract
This paper describes an improved Rate-Distortion Optimization Algorithm for JPEG2000. We proposed a new optimal constant setting method and rate allocation method to reduce execution time of the rate control. And we proposed hardware structure of the improved R-D opti. algorithm. Consequently, improved Rate-Distortion Optimization algorithm is faster than conventional rate control scheme in JPEG2000 standard and have nearly same performance.
