Abstract

This paper presents a region adaptive encoding scheme with JPEG decoder compatibility. This scheme adequately changes the Lagrange multiplier in R-D cost function for each block according to the segmentation information so that the important region for diagnosis can be coded with less distortion. The results show that the proposed scheme not only outperforms original JPEG but also outperforms R-D optimal thresholding JPEG in important regions with respect to image fidelity.
