Image Watermarking Scheme Using Singular Value Decomposition and Micro-genetic Algorithm
Chih‐Chin Lai, Hsiang-Cheh Huang, Cheng-Chih Tsai · 2008
In this paper, we introduce a novel image watermarking scheme using singular value decomposition (SVD) and micro-genetic algorithm (micro-GA). In an SVD-based watermarking scheme, the singular values of the cover image are modified by multiple scaling factors to embed the watermark image. The proper values of scaling factors are optimized and obtained efficiently by means of the micro-GA. Experimental results are provided to illustrate the feasibility of the proposed approach.
