| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose embedding method for digital watermarking by replacing basis images. Images can be represented as linear combination of basis images, which are constructed by independent component analysis. The basis images are similar to simple cells in receptive field on the primary visual cortex. Therefore, reconstructed image with the basis images still has specialty of its image. The basis images are generated from an original image.In this report, we embed a binary logo mark as a watermark by replacing one of basis images with the watermark.The replaced basis image is selected according to contribution ratio.Since the reconstructed image is constructed from basis images and logo mark, the watermark is widely distributed in the image.In order to extract the logo mark from the reconstructed image,basis images are regenerated from the reconstructed image.The logo mark can be constructed from some basis images which have higher contribution ratio.We can construct the logo mark with low bit error rate. |
