High Capacity Information Hiding Algorithm for DCT Domain of Image

The reason why only small capacity information can be hidden in DCT domain of image is analyzed, a information hiding algorithm of high capacity for DCT domain is proposed. In our scheme, the uniform spectrum processing is first applied to the original image. Then, a global DCT transformation of the...
