The name JPEG stands for Joint Photographic Experts Group, the name of the committee that created the JPEG standard and JPEG may not be as well suited for line drawings and other textual or iconic graphics, where the sharp contrasts between adjacent pixels can cause noticeable artifacts. Such images may be better saved in a lossless graphics format such as TIFF, GIF, PNG, or a raw image format. The JPEG standard actually includes a lossless coding mode, but that mode is not supported in most products
and there is a good report available abou ....etc

The attached utility is a work I've submitted to the university. It shows what a jpeg compression is all about.The function implements the DCT transform, using a matrix operator. Note that MATLAB has a function for the DCT and iDCT transforms that might be more efficient.Read the ReadMe.txt for some details about the algorithm. ....etc

Abstract
Detection of double joint photographic experts group (JPEG) compression is of great significance in the field of digital forensics. Some successful approaches have been presented for detecting double JPEG compression when the primary compression and the secondary compression have different quantization matrixes. However, when the primary compression and the secondary compression have the same quantization matrix, no detection method has been reported yet. In this paper, we present a method which can detect double JPEG compressi ....etc
