Evolutionary Computation Methods in Image Watermarking
Ahmed A.Saleh, Mohamed A. Abdou · International Journal of Computer Applications · 2013
Watermarking can be described as a desirable alternative solution for copyright protection of digital materials like images, video and audio.This paper introduced a modified watermarking method in Wavelet domain to get better performance.Particle Swarm Optimization (PSO) is used to find the best DWT coefficients in the HL sub -band for embedding the watermark sequence and PSO fitness function can be formed from the watermarked image with the best possible quality, and proved execution time.
