ABSTRACT: Perceptual image quality assessment uses various computation models to measure image quality by considering subjective evaluation. In recent years, according to the psychologists, neurobiologists study has shown that, which areas of image will attract most attention of human visual system. If distortion occurs in image, it will largely affect its visual saliency map. By considering this feature, in project work simple metric called visual saliency based index (VSI) is proposed to analyse image quality. Visual system is used to indicate local quality of the distorted image and to represent importance of local region in image. Several computational models are exist for computing VS maps. Comparison of various visual saliency models has done to analyse image quality.
