A Survey on Reversible Data Hiding
Amita Anil Ghadyalji | Dr. Prashant V. Ingole
Abstract: The conventional reversible data hiding (RDH) algorithms pursue high Peak-Signal-to-Noise Ratio (PSNR) at certain amount of embedding bits. But now-a-days, improvement of image visual quality is more important than keeping high PSNR. Based on this viewpoint, a novel RDH scheme, utilizing contrast enhancement to replace the PSNR is presented with the help of integer wavelet transform (IWT). To overcome the problem of over-enhancing of image, again a new RDH scheme is proposed using the controlled contrast enhancement (CCE) and integer wavelet transform (IWT). The proposed scheme will analyze various types of wavelet transform that are best suitable in given situation and will also have large embedding capacity while maintaining satisfactory visual perception with improved security.
