An image quality assessment algorithm used for JPEG compressed image

Theoretically speaking, image quality assessment algorithms are design to evaluate all kind of distorted images. However, as the JPEG compressed image dramatically distinguished from images with white noise, every distortion type has its own characteristic. A new method is proposed based on the characteristic of JPEG compressed image, witch correlated well with the subjective result.© (2007) COPYRIGHT SPIE--The International Society for Optical Engineering.
