Research ArticleOpen accessIn the abstractCombined DWT-DCT Digital Image WatermarkingAli Al-HajThe proliferation of digitized media due to the rapid growth of networked multimedia systems, has created an urgent need for copyright enforcement technologies that can protect copyright ownership of multimedia objects. Digital image watermarking is one such technology that has been developed to protect digital images from illegal manipulations. In particular, digital image watermarking algorithms which are based on the … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 18,200 accessesView PDF Cite

Research ArticleOpen accessIn the abstractColored Digital Image Watermarking using the Wavelet TechniqueMohammed F. Al-Hunaity, Salam A. Najim, Ibrahiem M. El-EmaryWith the revolution of information technology and Wide Area Networking, data has become less and less private where the access of media as well as the attempts to change and manipulate the contents of media data have become a common case. For that, we need to use a watermarking technique to protect the copyright of the media as well as … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,661 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLICENSE PLATE LOCALIZATION USING GABOR FILTERS AND NEURAL NETWORKSSami Ktata, Faouzi Benzarti, Hamid AmiriVehicle License Plate Detection (LPD) is an important step for the vehicle plate recognition which can be used in the intelligent transport systems. Many methods have been proposed for the detection of license plates based on: Mathematical morphology, Discrete Wavelet Transform, Hough Transform and others. In general, an LPR system includes four main parts: Vehicle image acquisition, license plate detection, … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,977 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGraph Based Segmentation in Content Based Image RetrievalP. S. Suhasini, K. S.R. Krishna, I. V.M. KrishnaProblem statement: Traditional image retrieval systems are content based image retrieval systems which rely on low-level features for indexing and retrieval of images. CBIR systems fail to meet user expectations because of the gap between the low level features used by such systems and the high level perception of images by humans. To meet the requirement as a preprocessing step … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,581 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Study of Thermal Contact using Nonlinear System Identification ModelsM.H. Shojaeefard, K. Goudarzi, A.R. Noorpoor, M. FazelpourOne interesting application of system identification method is to identify and control the heat transfer from the exhaust valve to the seat to keep away the valve from being damaged. In this study, two co-axial cylindrical specimens are used as exhaust valve and its seat. Using the measured temperatures at different locations of the specimens and with a semi-analytical method, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,528 accessesView PDF Cite
