Abstract:

The characteristics of JPEG2000 compression stream are studied and an image distortion model is proposed. By transferring the error rate of JPEG2000 compression stream to the error rate of bit channel coding data, and analyzing the different impact of channel error on JPEG2000 compression stream, the relationship between the image distortion and the error rate of bit channel coding is established. Simulation results show that the distortion value calculated by our proposed algorithm matches well with the actual value, which could be a good reference for estimating image distortion on the receiver.

Key words: information processing technology, JPEG2000, error rate, distortion model
