JPEG is an international standardization group whose purpose is to define standard algorithms for continuous-tone still images. In this thesis, we implement the JPEG specification fully and evaluate the performance of the JPEG image compression system. We also evaluate through experiments the parameter that controls the image compression ratio and the quality of reconstructed images.
A high compression ratio can be achieved by allowing endurable loss of image information. We evaluate the parameter that determines the compression ratio and the quality of reconstructed image with respect to the statistical characteristics of the image. Experimental results show that the parameter value varies significantly depending on the statistical characteristics of the image to achieve the same compression ratio.
