In this paper, we introduce an image watermarking scheme using singular value decomposition (SVD) and improved micro-genetic algorithm (micro-GA). In an SVD-based watermarking scheme, the singular values of a cover image are modified by multiple scaling factors to embed the watermark image. Determining proper values of scaling factors to reduce visual artifacts is viewed as an optimization problem...
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...
