Improved pixel hiding method for steganography of gray images within color images

Steganography is the process of data hiding into a host signal with three main characteristics: imperceptibility, payload and quality of the recovered data. For images, one of the pixel modication methods is the BPHM (Block Pixel Hiding Method) which has good imperceptibility and payload, but it doe...
