摘要: In this paper, a novel blind watermark extracting scheme using the Discrete Wavelet Transform (DWT) and Particle Swarm Optimization (PSO) algorithm is introduced. The embedded to discrete multiwavelet transform (DMT) coefficients larger than some threshold values, extraction efficiently performed via particle swarm optimization algorithm.The experimental results show that proposed watermarking in an almost invisible difference between watermarked image original image, robust common processing operations JPEG lossy compression.
