Adaptive JPEG steganography based on distortion cost updating

Adaptive JPEG steganography based on distortion cost updating

Previous adaptive JPEG steganography algorithms mostly calculate image distortion before secret information embedding,so they can’t dynamically adjust distortion costs.Considering the mutual impacts during embedding,an adaptive JPEG steganography algorithm based on distortion cost updating was propo...
