Abstract
This paper narrates infrared image watermarking based on the discrete Shearlet transform(DST). DST has nice multiresolution and multi-directional[1] analysis ability. This feature of DST can be exploited on image watermarking. the proposed method has two purposes. One is hiding watermark information into multi-direction coefficients of the host infrared image to make the watermark is imperceptibility. The other purpose is dealing with various attacks such as noise addition, enlarging, cropping, median filtering and Gaussian filtering to verify the robustness of this method. The experimental results show that the visual effect is satisfactory because the secret information can’t be distinguished by people’s eyes. In fact, through the correlation calculation also shows that the invisible effect is very good.
