Image Watermarking System Based on Centroid Projection
We propose an image watermarking system aiming at reducing false positive rate based on the location changes of centroids of several selected points. Two secret keys are used to determine the number of selected points and the random number seed in the LL band of DWT domain, respectively, of the o r i g i ~ l and watermarked images. The number of modified pixel values is basically a tradeoff bet...
متن کاملA feature-point-based RST resistant watermarking scheme
This paper presents a feature-point-based rotation, scaling, and translation (RST) resistant digital watermarking scheme. The improved Harris detector locates the robust and important feature points, which are further used by the acute triangle matching to determine the possible geometric attacks for reducing synchronization errors. The human visual system compatible mid-frequency embedding str...

متن کاملA Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
