Description
| - V této práci, jsou prezentovány principy vodoznaku. Navrhovaný systém je založen na chaotické funkci pro vkládání a srovnávací metodě pro detekci. Použitý princip ukazuje zvýšenou odolnost proti JPEG kompresi a filtraci. (cs)
- In this work, a new blind watermarking scheme in frequency domain is presented. The proposed scheme is based on a chaotic function for embedding, and a correlation method for detection. Three-dimensional maps of PSNR and correlation are used for better selection of embedding parameters according to a duality threshold. The scheme shows increased robustness against Jpeg compression and cropping. The watermark is also detectable after filtering attacks like low pass filtering, median filtering and Gaussian blur, noise attacks, as well as some geometrical attacks
