Background: De-noising is the main effect produced by image compression at low compression ratios, which alters only the noise parts of images. The difference between the original and manipulated images will be less than the statistical variation when pixel values are sampled from these two images. This study develops a method that determines the quality indication in images using compression. Keywords: Image compression, JPEG 2000, Kolmogorov-Smirnov test, PSNR, statistically lossless.
