Which gray level should be given the smallest cost for adaptive steganography?


Currently, the most successful approach to steganography in digital image is distortion-minimization framework, which reduces the steganographers’ work to the design of distortion function with the aid of practical coding schemes. Previous distortion functions for spatial images are all position dependent, in which cost is determined by the relationships… (More)
