Singular Value Decomposition technique for digital image watermarking
Namrata Singh · 2009
This paper aims at embedding an invisible watermark into a digital image using the Singular Value Decomposition (SVD). The technique uses the U matrix of the SVD and modifies two of its value according to the watermark bit. The proposed technique is more robust and secure over a recent scheme proposed by B. Chandra Mohan and S. Srinivas Kumar in terms of Bit Correct Rate. Superior results are obtained when the watermarked image is attacked by histogram equalization, cropping, setting and resetting LSB plane, linear and non-linear filtering, noise and compression.
