A robust digital watermarking method for textile image

Abstract

In this era of rapid development of network, the infringement of the textile industry is becoming more and more important, which seriously restricts the development of textiles. In this paper, a robust digital watermarking method based on chrominance and texture features of textile images is proposed. The cover image was transformed into CIE LAB color space, and the B channel of the cover image was extracted. The B channel of the carrier image was divided into blocks, and each image block was transformed by DCT. In order to better to maintain the visual effect of the image and the robustness of the watermark, the watermark is embedded in the intermediate frequency domain of DCT. Then the digital image is transferred to the textile by using the dark transfer film through the thermal transfer printing technology. The experimental results indicate that the method is robust to the attack of textile image in the process of print-canning. And the method could coordinate the contradiction between invisibility and robustness.
