The present paper proposes a novel method for grayscale image steganography based on edge detection and adaptive multiple bits substitution. Compared with the smooth regions, the pixels located in the edge regions usually present more random characteristics. In proposed method, the gradient magnitude of the pixels of the cover image is computed using the Sobel operators. As a result, all edges of the cover image, both horizontal and vertical, are fully detected. According to the length of… CONTINUE READING
