| Abstract(in English) | We have recently discussed digital watermarking techniques based on modifying the spectral coefficient of an image, and have presented a model of the watermark embedding and extracting processes and a model of watermark distortion caused by image processing and attack of watermarked image. In this paper, based on these models, we formulate the watermark detection problem as a kind of blind deconvolution problem. Then, as a solution to this problem, we propose a watermark detection method using Bayesian estimation. |
