2012 19th IEEE International Conference on Image Processing, 2012•ieeexplore.ieee.orgWe propose a statistical model of natural images in JPEG format. The image acquisition is
composed of three principal stages. First, a RAW image is obtained from sensor of Digital
Still Cameras (DSC). Then, the RAW image is subject to some post-acquisition processes
such as demosaicking, white-balancing and γ-correction to improve its visual quality. Finally,
the processed images goes through the JPEG compression process. For each step of image
processing chain, a statistical study of pixels' properties is performed to finally obtain a …
