Steganography based on quotient value differencing and pixel value correlation
Abstract Pixel value differencing (PVD) steganography techniques produce imperceptible stego‐images. Most PVD‐based techniques have a fall‐off boundary problem (FOBP). To avoid FOBP, a steganographic scheme is presented that combines the quotient value difference (QVD) with pixel value correlation (...
