| Abstract: | A self-detection watermarking algorithm for vector data was proposed using logical blocking and quantization ways.Then,the experiments for testing the robustness of self-detection were conducted.And a research was made on the application of the proposed self-detection algorithm to the area of improving watermarking detection efficiency.The experimental results show that the algorithm is with good robust and can resist some usual attacks such as data compressing,adding,deleting,editing,clipping,translating.A... |
