A DWT digital watermarking algorithm based on HVS
Wang Bai-xiang · Journal of Zhejiang University(Science Edition) · 2013
With the development of internet,exchange and transmission of digital data become easier and faster than before.The technology of digital watermark is a new technique for protecting the copyrights of digital products by embedding some numbers,serial numbers or maps in original digital products.In this paper,a kind of blind digital watermark based on HVS and DWT was proposed,and this kind of algorithm could effectively achieve the balance between robust and imperceptibility in watermarked image by using HVS algorithm.It showed that the proposed algorithm had good property of robust and imperceptible by Matlab software stimulation experiments.
