Fidelity Analysis of Additive and Multiplicative Watermarked Images in Integrated Domain
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 5
Abstract
Abstract: The escalation of internet has increased the usage of multimedia contents for wide range of functions. The easy access of the digital contents paves way to manipulate, edit and duplicate the contents using available image processing software. Watermarking process ensures copy protection and data authentication to the multimedia content by embedding watermark. The present paper proposes fidelity analysis of additive and multiplicative watermarked images in the integrated domain using Peak Signal to Noise Ratio measures. This paper first embeds additive watermark in spatial domain and multiplicative watermark in frequency domain, then vice versa. The later one provides good fidelity and less image degradation by achieving acceptable Peak Signal to Noise Ratio values.
