A watermarking scheme for digital images based on Particle Swarm Optimization (PSO) in the Discrete Wavelet Transform (DWT) is proposed. The watermark is inserted into the DWT subbands which have the most important coefficients. The robustness of proposed scheme is empowered by applying the PSO. PSO optimizes the imperceptibleness of the watermark and the quality of the watermarked image which results in identifying the optimal / nearly optimal embedding positions. A series of experiments were… CONTINUE READING
