PSNR is a good measure for comparing restoration results for the same image, but between-image comparisons of PSNR are meaningless. I tried to use imwrite, but it doesn't save axes in image. Quantization Image using MATLAB. For example if you have an image that is 300dpi at its original size and you add this image to a double-page spread, it will reduce in resolution accordingly as it expands to fill the larger space. Each metric has a different computational complexity and agreement with the human perception of image quality. Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. It originates due to extra information added in the image wherever a lack of information exists. For the triangulated surface example, MATLAB generates a much bigger file though.
