Abstract : No-reference image quality assessment is a category of image quality assessment algorithms which gives the
estimate of the quality of an image without the requirement of a reference image. Storage of high definition images in low
end storage systems needs quantization. Excessive quantization of gray levels or color results in degradation of quality of
images. In this paper, we propose a no-reference image quality assessment algorithm based on image histogram which gives
an estimate of quality of images which are degraded by excessive quantization of gray levels or colors. The proposed Image
Quality Assessment measure performs better than the best known Image Quality Assessment measures for images with
quantization noise on standard datasets.
