[ 1 ] - نهان‌کاوی در تصاویر JPEG بر مبنای دسته‌بندی ویژگی‌های آماری و تصمیم‌گیری دو مرحله‌ای

Abstract In this paper, we propose a comprehensive steganalysis scheme for JPEG images. In this method, the optimized features which can interpret high distinction between cover and stego images are extracted from images. These features have been selected after a careful study on modifications caused by different steganography algorithms on statistical characteristics of images. Furthermore, us...
