A high capacity data hiding scheme based on edge detection and even-odd plane separation

In this paper a high capacity data hiding technique based on hybrid edge detection and even-odd pixel separation is proposed. The even-odd sub planes of Red, Green and Blue of the cover image are extracted then Blue and Green channel sub planes are utilized for hiding the secret data while Red channel sub planes are used to hold the status (edge or non-edge) of the pixels of Green and Blue channel sub planes. The experimentation has been carried out for different capacities of data bits and the results are compared with a state of art data hiding technique which reveals that the proposed technique has high capacity. Further good quality stego-images are obtained.
