基于人眼视觉特性的DCT域的信息隐藏盲提取算法
A Blind Information Hiding In DCT Domain Based on Human Visual Characteristic
摘要
Abstract
By the characteristic analysis carried on Human Visual System and DCT transformation,mide frequency section in DCT coefficient of carrier images is selected as DCT coefficient of the images to be hided.The DCT blocks of a cover-image are classified into three classes based on Human Visual System(HVS) characteristics,and then the parameters to be changed in each quantized DCT coefficient of a DCT block is varied with the type of the block.The experimental results indicate that this algorithm possesses very good steganography and strong robustness.Besides,the embedding data can be extracted from the stego-image without referencing to the original cover-image.关键词
