A Survey on Digital Image Authentication by DCT and RPM Based Watermarking
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 4
Abstract
Abstract: An image watermarking, data is embedded into cover media to prove ownership. Various Watermarking techniques are proposed by several authors within the last many years that embody spatial domain and transform domain watermarking. This paper elaborates quality of discrete cosine transform forimage watermarking, DCT primarily based image watermarking method, classification and analysis of discrete cosine transform based mostly watermarking techniques. The aim of this paper is to produce a comprehensive review of the existing literature available on discrete cosine transform and wavelet based mostly image watermarking ways. It’ll be helpful for researchers to implement effective image watermarking methodology.
