Abstract

Selecting an appropriate quantization table for Joint Photographic Exploitation Group (JPEG) data compression of a class of images can be an arduous task. We have designed a graphical user interface to study the effects of quantization on compression ratio and the resulting image quality. The tool calculates several measures of the difference between the original and lossy compressed image. Some of these measures are entropy, mean square error, and normalized mean square error. These measures aid the user in selecting the optimal quantization values with respect to image fidelity and compression ratio for a particular class of images.
