Abstract : This paper presents a no-reference image quality assessment model for JPEG/JPEG2000 coding. This assessment model are based on the blockiness around the block boundary, the average absolute difference between adjacent pixels within block, and the zero-crossing rate within block. The descrimination of JPEG coded image and JPEG2000 coded image is performed using the information of the blockiness and the average absolute difference between adjacent pixels. For image quality assessment of JPEG2000 coding, the blur measure is introduced instead of the blockiness of JPEG coding.
