Abstract
In this paper a robust Hybridized Watermarking scheme based on Fast Walsh Hadamard transform (FWHT) and Singular Value Decomposition (SVD) using Genetic algorithm (GA) is presented. The host image is subjected to FWHT and SVD . The singular values of SVD of host image are modified with singular values of watermark. Multiple scaling factors are used in watermark embedding. The GA searches for optimized multiple scaling factors from a random population using a fitness function. When the optimized multiple scaling factors are applied dramatically lot of improvement is seen in robustness without losing the transparency.
