| Abstract(in English) | This paper proposes a watermarking method varies the frequency into where an watermark element is embedded according to blocks. The proposed method generates the watermarked images with a desired image quality in terms of the Peak Signal-to-Noise Ratio, and extracts a embedded watermark without any reference images. Selecting the frequency for embedding according to blocks makes the visibility of watermark in the spatial domain variable, and makes detecting the embedding frequency without any key difficult. Simulation results show the effectiveness of the proposed method. |
