Because of the fast developing technologies in multimedia devices, we are able to receive huge amounts of images from daily life. Once these images have been stored, the next step is to figure out how to retrieve the desired pictures quickly and accurately from the database. In this paper, we intend to develop an efficient image retrieval algorithm. Using(More)
In this paper, we propose a novel blind steganalytic scheme able to detect JPEG stego images embedded with several known steganographic programs. By estimating the original image of the given image, thirteen types of statistics are collected in the DCT domain and the decompressed spatial domain. Then we calculate the histogram characteristic function (HCF)(More)
