In this paper, we propose a binary value based progressive image watermarking approach for digital right protection. The proposed method embed most watermark information into region of interest(ROI) of an image. Therefore, a client on Internet can decode the watermark while receiving the image, moreover, most watermark information would be decoded while the ROI of the image is received. In order to...
In this paper, we propose a digital watermarking method for stereoscopic video frames. A stereoscopic video frame is stored as two images and combined by software while displayed. These two stored images are with high similarity. In the circumstances, it should be taken into consideration to resist coalition attacks while developing a watermarking scheme for stereoscopic videos. As shown in experimental...
In this paper, we propose a binary value based progressive image watermarking approach for digital right protection. First, a new binary valued watermarking method for wavelet domain images are introduced, and then a progressive watermark detecting scheme for Internet environment is introduced. Its performance was evaluated with two types of experiments (1) robustness against image attacks and (2)...
Digital watermarking, in conjunction with cryptography, is one of the two major categories for information security. Unlike cryptography that the encrypted information represents like noisy patterns, by using watermarking, the watermarked contents look almost identical to its original counterpart, while it still retains the capability to counteract intentional signal processing by others and keeps...
