Steganographic Method Based on FCM and HVS

To provide larger capacity of the hidden secret data and to maintain a good visual quality of stego-image,in terms of contrast and gradient sensitivity,the paper puts forward a steganographic method based on FCM (Fuzzy C-means Clustering) and HVS (Human Visual System),by making use of the classification ability of fuzzy clustering. This method uses contrast and gradient sensitivity as feature vector,and divides pixels into the sensitive class and insensitive class by FCM. More secret data can be embedded in the pixels of insensitive class with steganography based on modulus,and data with little secret can be embedded in the pixels of sensitive class. The experimental results show that the proposed method hides much more information compared with SMFH.
