Research ArticleOpen accessIn the abstractFish Recognition Based on Robust Features Extraction from Size and Shape Measurements Using Neural NetworkMutasem Khalil Alsmadi, Khairuddin Bin Omar, Shahrul Azman Noah, Ibrahim AlmarashdehProblem statement: Image recognition is a challenging problem researchers had been research into this area for so long especially in the recent years, due to distortion, noise, segmentation errors, overlap and occlusion of objects in digital images. In our study, there are many fields concern with pattern recognition, for example, fingerprint verification, face recognition, iris discrimination, chromosome shape discrimination, optical … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 9,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvariant Image Watermarking Using Accurate Zernike MomentsIsmail A. Ismail, Mohamed A. Shouman, Khalid M. Hosny, Hayam M. Abdel SalamProblem statement: Digital image watermarking is the most popular method for image authentication, copyright protection and content description. Zernike moments are the most widely used moments in image processing and pattern recognition. The magnitudes of Zernike moments are rotation invariant so they can be used just as a watermark signal or be further modified to carry embedded data. The computed … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jul 2010 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperiment of Tamper Detection and Recovery Watermarking in Picture Archiving and Communication SystemsSiau-Chuin Liew, Jasni Mohamad ZainProblem statement: Medical images such as x-rays, ultrasounds and Magnetic Resonance Imaging (MRI) plays an important role in helping the physicians to diagnose a disease or body conditions. These images can be tampered with existing image processing tools that is easily available. The usage of security measures such as watermarking can protect the integrity of the images. Numerous watermarking schemes … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Classify Noises in Images Using Artificial Neural NetworkT. Santhanam, S. RadhikaProblem statement: Noise identification is predominant in any digital image processing algorithms, which helps in identifying the filters to smooth the image for further processing. Approach: An Artificial Neural Network (ANN) based approach was proposed for noise identification. The suggested technique involved seclusion of the noise samples and extracts their statistical features, which was then applied to a neural network … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Methodology for Designing Radix-2n Serial-Serial MultipliersAbdurazzag Sulaiman AlmiladiProblem statement: The fast growth and increase in complexity of digital and image processing systems necessitate the migration from ad hoc design methods to methodological ones. Methodologies will certainly ease the trade off selection for those systems and shortens the design time. To increase those gained values and expand the searching space more appropriate methodologies need to be developed. Approach: … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Implementation of Truncated Multipliers Using Spartan-3AN, Virtex-4 and Virtex-5 FPGA DevicesMuhammad H. RaisProblem statement: The development cost for Application Specific Integrated Circuits (ASICs) are high, algorithms should be verified and optimized before implementation. The Digital Signal Processing (DSP), image processing and multimedia requires extensive use of multiplication. The truncated multipliers can easily be implemented using Field Programmable Gate Array (FPGA) devices. Approach: This research presented the comparative study of Spartan-3AN, Virtex-4 and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,334 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Morphological Method for Detection and Recognition of Vehicle License PlatesS.H. Mohades Kasaei, S.M. Mohades Kasaei, S. A. MonadjemiProblem statement: License plate detection and recognition is an image-processing technique used to identify a vehicle by its license plate. This notable technology has got multiple applications in various traffic and security cases. To name but a few, toll roads, border control, security and car tracking are same of its applications. The main stage is the isolation of the license … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,653 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital Video Watermarking in the Discrete Cosine Transform DomainSadik Ali M. Al-Taweel, Putra Sumari, Saleh Ali K. Alomari, Anas J.A. HusainProblem statement: Nowadays, digital watermarks have recently become recognized as a solution for protecting copyright of the digital multimedia. For a watermark to be useful, it must be perceptually invisible and robust against any possible attack and image processing by those who seek to corsair the material, researchers have considered various approaches like JPEG compression, geometric distortions and noising. Approach: … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractBinary Merge Coding for Lossless Image Data CompressionN. Subhash Chandra, M. Bala Raju, M. Arya bahanu et al.Problem statement: Image processing applications were drastically increasing over the years. In such a scenario, the fact that, the digital images need huge amounts of disk space seems to be a crippling disadvantage during transmission and storage. So, there arises a need for data compression of images. Approach: This study proposed a novel technique called binary merge coding for lossless … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 6,861 accessesView PDFCite
