High capacity video steganographic algorithm based on visual perception model
基于视觉感知模型的大容量视频隐写算法

In order to provide large capacity of steganography and maintain a good visual quality of stego-video,a novel high capacity video steganographic algorithm based on visual perception model is presented. This algorithm integrates multi-parameter spatial contrast sensitivity function,contrast masking based on classification of DCT blocks,and motion attention. Then secret information is embedded under control of distortion masking measure of each DCT coefficient. Experimental results show that the new algorithm...
