Effects of Directional Subdividing on adaptive Grid-Embedding (RESEARCH NOTE)
The effects of using both directions and directional subdividing on adaptive gridembedding on the computational time and the number of grid points required for the same accuracy are considered. Directional subdividing is used from the beginning of the adaptation procedure without any restriction. To avoid the complication of unstructured grid, the semi-structured grid was used. It is used to so...
متن کاملDirectional Based Watermarking Scheme Using a Novel Data Embedding Approach
Image watermarking has come to wide use in the recent past. It is by the authentication problems and limitation means that the setting accuracy of the image watermarking operation is minimized. Different types of integration schemes have been proposed in the past to improve efficiency and makes the embedding resistant against various attacks .Although transformation, spatial domain approaches h...
متن کاملAn Improved Robust and Adaptive Watermarking Algorithm Based on DCT
This paper proposes an improved watermarking algorithm based on DCT (Discrete Cosine Transform). We carried out the algorithm as described as follows. First, we extended both rows and ranks of the watermark by using the proposed method before the embedding stage. After expansion, Sine chaotic system is employed in encrypting the watermark. In the embedding stage, an effective and adaptive embed...
متن کاملReversible Watermarking Algorithm Based on Embedding Pixel Dependence
Many works have demonstrated that the performance of the prediction error (PE) based reversible watermarking algorithm depends on the precision of the prediction value. However, most algorithms compute the prediction value by exploiting only the correlation between the embedding pixel and its neighboring pixels, thus limiting the watermarking performance of these algorithms. In this work, we ob...
متن کاملResearch on Color Watermarking Algorithm Based on RDWT-SVD
In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...
