Abstract :
The efficient use of channel bandwidth is one of the main issues in transmitting of image/video data. Rate control or rate allocation is necessary to control the bitrate of image coding such that it meets the channel bandwidth requirement. In this paper, we present a modified coding scheme based on region quality using JPEG2000. This scheme can achieve efficient utilization of the bandwidth as well as a high compression ration, which enables it play an important role in many fields such as transmission of satellite image, medical image and image communication in 3G.
