- Abstract
Intangible cultural heritage is an important symbol to recognition different ethnics. In order to enhance the copyright protection and authentication of intangible cultural heritage, this paper presents a novel way to process the carried image that Li brocade. Firstly, Li brocade image was decomposed into a new image that has four different components of low frequency, horizontal, vertical and diagonal image features though DWT transformation, then the low frequency component was processed by the whole DCT transform to eliminate coefficient correlation for obtaining an image, which was well suitable for the human visual system. Secondly, employing the bit operation of Hash function (OR), between the encrypted watermarking and visual feature vector, to realize the watermarking embedding and protect some information. Finally, the watermarking image is extracted by blind watermarking algorithm. The simulation results show this method not only has ultra-robustness and imperceptivity, but also can resist greater geometrical attack than others, thus, it has better application value in protecting the copyright of Intangible Cultural Heritag
