Reversible Watermarking Using IWT For DifferentImages

Wavelets were developed independently by mathematicians, quantum physicists, electrical engineers and geologists, but collaborations among these fields during the last decade have led to new and varied applications. What are wavelets, and why might they be useful to you? This paper will tell you how Reversible watermarking has found a huge surge of experimentation in its domain in past decade as the need of recovering the original work image after extracting the watermark arises in various applications such as the authentication, law enforcement, medical and military applications, it is crucial to restore the original image without any distortions.
