Research ArticleOpen accessPhrase in the titlePerformance Optimization of Discrete Wavelets Transform Based Image Watermarking Using Genetic AlgorithmsA. Al-Haj, A. Abu-ErrubThe excellent spatial localization, frequency spread and multi-resolution characteristics of the Discrete Wavelets Transform (DWT), which were similar to the theoretical models of the human visual system, facilitated the development of many imperceptible and robust DWT-based watermarking algorithms. There had been extremely few proposed algorithms on optimized DWT-based image watermarking that can simultaneously provide perceptual transparency and robustness since these … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,324 accessesView PDFCite

Research ArticleOpen accessIn the abstractImage Recognition Using Combination of Discrete Multi_Wavelet and Wavenet TransformDr Mikhled AlfaouriFocus of the method was to present image identification and labeling using new combination of dynamic transforms. This method is based on using the combination of the Discrete Multi-wavelet Transform (DMWT) and Wavenet Transform (WN). In this method, the resulting coefficients were computed by the proposed multi-wavelets transform for single-level decomposition. The low pass sub bands of the upper left … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,088 accessesView PDFCite
