Abstract
In the current scenario, the need for security in Image processing seems to be more significant. Digital watermarking is one such feature extraction. Generally PCA (Principle Component Analysis) method is used for feature extraction. A new methodology based on ‘Energy Analysis’ is proposed in this research work for feature extraction. Optimization techniques are used to enhance resolution and authentication of the image. The watermarked image can be hidden in the original image using 2-level DWT and as a final point watermarked image is created in wavelet domain. For a complementary watermark modulation, the perceptual lossless ratio (PLR) is initially derived in this proposed technique. From the simulation results, optimal values are calculated and compared for both Genetic Algorithm (GA) and Particle Swarm Optimization (PSO).

Key words: Principle Component Analysis, 2-level DWT, Perceptual Lossless Ratio (PLR), Robustness, Optimal Values, Genetic Algorithm (GA), Particle Swarm Optimization (PSO).
