System and Method for robust lossless data hiding and recovering from the integer wavelet representation |
摘要 |
A method is provided which comprises providing a block of IWT (integer wavelet transform) coefficients for preferably one high frequency sub-band of an image; determining a mean value of said coefficients within said block; and establishing an encoded mean value to embed one of a logical-0 bit value and a logical-1 bit into said first block. |
