Literature Review of Dual Data Hiding and Image Compression and Digital Inpainting

This paper presents a review of dual data hiding and image compression techniques and digital inpainting. Reversible data hiding plays important role in information security. A technique image compression is followed by data hiding scheme. Data hiding and image compression is two independent modules at user and receiver side. A method of digital inpainting is used to remove/replacement of unwanted objects of media. Digital inpainting consists of inpainting of audio, video and image. The goal of any digital image inpainting algorithm represents a reconstruction of the misplaced or scratched regions in a visually plausible way. First the Classification of reversible data hiding techniques are introduced, then types of digital inpainting methods. There are various applications of data hiding techniques and digital inpainting. Also advantages and limitations of these methods are discussed in detail.
