An High Performance Information Hiding Scheme Based on CL multi-wavelet and Color Transfer Theory for Secret Communication

This paper takes advantage of the feature that the energy of the image would gather and spread on four components (LL2, LH2, HL2 and HH2) in the sub-image after first-order CL multi-wavelet transform. The authors make use of the color control ability of 1 alpha beta color space in color transfer theory. They propose a reversible information hiding algorithm named CL-CTT. They use color transfer theory to generate the embedding rule. Experimental results indicate that CL-CTT can increase imperceptibility by 19.40% averagely and robustness by at least 19.99% and have excellent sensitivity of image processing.
