%X A blind detection method of digital watermark based on coordinates calibration is proposed in this paper.The watermark array is first permuted for the sake of security.Then the binary watermark is embedded into the original host image,and the coordinates information are blended in the same image as well.Therefore,the coordinates can be calibrated for restoring watermark from the right place.Simulation results show that the proposed method can realize blind detect for watermark,and is of high security.It is robust to cutting interception,JPEG compression,additional noise,mean filtering,and also cutting in real sense.
