A Novel Zero-watermarking Algorithm Based on DWT and Edge Detection
This paper introduces a novel zero-watermarking algorithm based on DWT and edge detection. According to the images low frequency component, the algorithm extracts the interested main information from an original image after two-level DWT and then transfers this information to a matrix by a coding method. Do the XOR operation to this matrix with the watermark image to get a pseudo-watermark and achieve the aim of information hiding. On account of the property of zero-watermarking, technically, this algorithm has overall good robustness and large watermark capacity. Such property had also been verified by experiments.
