Abstract: In this paper, an algorithm of digital image watermark based on frequency-refined multiresolution wavelet and quantization is introduced, and the original image is not required for detecting the watermark. Experimental results show that the proposed algorithmkeeps the quality of the image well and is robust against common image processing operations.
