Paper Abstract

We propose a novel watermarking method. The proposed method insets a watermark information not into a whole image region but only into interesting regions. To extract the interesting region, we divide an original image into sub- blocks by sing Chang's PIM criteria for a region segmentation. Considering a directional information and a frequency band, we insert the watermark information into the sub-block in DCT domain. With use of it, the proposed method gets a much less damaged image in comparison into the other methods. And this result image is more robust to the attacks form outside. Also the proposed method can reduce the distortion in comparison with the other methods which utilize the whole image as an interesting region.
