Abstract
In this paper, a simple approach is proposed to improve the performance of JPEG. In the proposed approach, the coding scheme is identical to the JPEG except only a fixed number of coefficients are coded for each image block. Consequently, it is totally compatible with the JPEG and is termed as zonal JPEG. Simulation results indicate that the proposed zonal JPEG is able to trade little PSNR with significant bit rate reduction when compared with thee JPEG.
