In this paper a watermark restoration algorithm based on synergetic associational neural network is presented. It employs synergetic computer theory to improve the robustness of the spatial watermark. The DES encrypted watermark is embedded into the host image by using the improved LSB algorithm. Multiple encrypted watermark images compose mode vectors to train synergetic neural network. Through synergetic association, the network imported by the extracted watermark can identify and restore the embedded watermark. Experimental results show that this algorithm can resist various signal processi...
