Abstract

Abstract

This paper considers the modei of optimal estimation of image information when some of the image data are lost due to transmission errors. A new technology is proposed for image recovery in transform coding based on the boundary information of adjacent blocks, the algorithm for estimating the optimal solution and the analytical form of the gain of SNR. Experimental results show that when SNR increases 10-20 dB, the visual quality can improve from 1 to 3 or 4. Compare with the other theme, the algorithm proposed in this paper improves the quality of both low and high frequency information and can easily be implemented.
