Abstract
A novel image watermark scheme based on the shuffled frog leaping (SFL) algorithm is proposed in the paper. The watermark is embedded to the discrete multi wavelet transform (DMT) coefficients larger than some threshold values, and watermark extraction is efficiently performed with SFL algorithm. Experimental results show both the robustness under attacks and the improvement in watermarked image quality with the proposed SFL algorithm.
