Research on Analysis of Statistical Performance of JPEG2000 Encoded Image over Wireless Channel and Error Protection Schema
JPEG2000 is a new image standard. In this paper, the performance of error resilience tools in JPEG2000 is analyzed at first, then an analytical model to estimate the quality of JPEG2000 encoded image transmitted over wireless channel is presented. The effectiveness of the analytical model is validated by simulation results. Furthermore, analytical model is utilized by the base station to design efficient unequally error protection (UEP) schemas for JPEG2000 image transmission. With the analytical model, a utility function is defined to make a tradeoff between the image quality and the cost for transmitting the image over wireless channel, and chose which kind of UEP schemas to employ to reach the optimal image transmission quality.
