This paper describes the image quality assessment techniques i.e used for assessing the qualities of the images sending over the different mediums. In this paper full reference model of objective quality assessment is used. Full reference model is a method, in which we have access to a „perfect version‟ of the image against which we compare it with a „distorted version‟ of that image. Paper describing how the quality of the image is affected after introduction of noise or other interference parameters. The effects are calculated in terms of some mathematical metrics PSNR, SNR and MSSIM. In this paper the concept of degradation in quality can be understand by comparison between the above metrics of original image with the distorted image. Finally results are drawn using the image processing toolbox in MATLAB.
