To increase the capacity of the hidden secret information and to provide a stego-image imperceptible for human vision, a novel steganographic approach based on pixel-value differencing is presented .This approach uses the largest difference value between the other three pixels close to the target pixel to estimate how many secret bits will be embedded into the pixel. The theoretical estimation and experimental results demonstrate that the proposed scheme can provide a superior embedding. Besides, the embedded confidential information can be extracted from stego-images without the assistance of original images.
