A new imagecoding method based on image region is proposed in this paper. According to the features of the image gray surface, an image is partitioned into many convex polygons which appoximate the original image as close as possible. The experimental results show that good quality of the reconstructed image can still be obtained when the data compression ratio is more than 20:1 and SNR is more than 30dB.
