Enhance Novel Joint Data-Hiding and Compression Scheme Based on exemplar approach
نویسنده
چکیده
The JDHC scheme not only focuses on the high hiding capacity and recovery quality, it also integrates the image compression and data hiding into a single module. joint datahiding and compression scheme by using SMVQ and PDE-based image inpainting. Image Inpainting refers to methods which consist with filling-in disappeared regions in a picture. Inpainting for digital images has found applications in such areas as repairing of damaged photographs, filling in or removing chosen areas, and wiping off visible watermarks. The exemplar based approach is an important class of inpainting algorithms. And they have proved to be very effective. The exemplar based approach samples the best matching patches from the known region, whose similarity is measured by certain metrics, and pastes into the target patches in the missing region.

To enhance the hiding capacity of DCT-based images, in this paper we propose a new data hiding scheme based on a notation transformation concept. Without considering the reversibility function, experimental results confirm that the hiding capacity provided by our designed data hiding strategy is not only higher than that provided by the Iwata et al.’s, Chang et al.’s and Lin et al.’s schemes bu...
