In Image quality evaluation is very important. In applications involving signal transmission, the Reduced-or No-Reference quality metrics are generally more practical than the Full-Reference metrics. This system deals with data hiding in compressed images. Unlike data hiding in images and raw video which operates on the images themselves in the spatial or transformed domain which are vulnerable to Steganalysis, this project target the motion vectors used to encode and reconstruct both the
