Image & Video Quality Assessment and Human Visual Perception

Images and videos have become an essential part of day to day life, we observe the images and videos and draw the conclusion that a particular image or video is of good quality or bad quality as lots of time we say that the particular video is a high definition video so some questions arise how we assess the quality of an image and video? What are the factors and parameters that make the image of good or bad quality? How the images and videos are perceived by the human eyes? So this paper is concentrated around all the issues related to the quality assessment of the images and the videos. This letter describes the state of art related to the image and video quality by utilizing the some pre-existing quality metrics like PSNR, SSIM and VQM etc. And it also give emphasize on the human visual perception that describes the sensitivities of human eyes towards the images and
