Research ArticleOpen accessIn the abstractComparative Study of Changing Drainage Basin System with Tectonic Forms, Case Study: Lut Block, IranEbrahim MoghimiThe study area locates in the east of Iran and it is morphologic block (unit). Problem statement: Sharp contrasts in the appearances of landscapes such as drainage basins with litology (kind of rock), tectonic regime, folding and climatic effect had been inspired geomorphologies in the past and now to devise schemes to explain those contrasts. These contrasts also remained and … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultimodal Integration (Image and Text) Using Ontology AlignmentAhmad Adel Abu Shareha, Mandava Rajeswari, Dhanesh RamachandramProblem statement: This study proposed multimodal integration method at the concept level to investigate information from multimodalities. The multimodal data was represented as two separate lists of concepts which were extracted from images and its related text. The concepts extracted from image analysis are often ambiguous, while the concepts extracted from text processing could be sense-ambiguous. The major problems that … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractIris Recognition Using Discrete Cosine Transform and Artificial Neural NetworksAhmad M. SarhanProblem statement: The study presented an efficient Iris recognition system. Approach: The design used the discrete cosine transform for feature extraction and artificial neural networks for classification. The iris images used in this system were obtained from the CASIA database. Results: A robust system for iris recognition was developed. Conclusion: An iris recognition system that produces very low error rates … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 7,760 accessesView PDFCite
Research ArticleOpen accessIn the abstractColor Image Reconstruction Using A New R'G'I ModelAkram A. Moustafa, Ziad A. AlqadiProblem statement: A new color model for digital image was discussed; this model can be used to separate low and high frequencies in the image without loosing any information from the image. Approach: A comparative study between different color models (RGB, HSI) applied to a very large microscopic image analysis and the proposed model was presented. Such analysis of different … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,493 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of MultiScale Hidden Markov Modeling Wavelet Coefficients to fMRI Activation DetectionFangyuan Nan, Yaonan Wang, Xiaoping MaProblem Statement: The problem of detection of functional magnetic resonance images (fMRIs), that is, to decide active and nonactive regions of human brain from fMRIs is studied in this paper. fMRI research is finding and will find more and more applications in diagnosing and treating brain diseases like depression and schizophrenia. At its initial stage fMRI detection are pixel-wise methods, … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Data Processing on Data QualityA. R. SamihProblem statement: Great attention had been paid on spatial data quality by the scientific community. This was due to the negative impact that a poor spatial data quality had on the competitiveness of an organization. On other hand, we can never obtain good quality data from a poor quality data. In this study, we demonstrate the effects of the different … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust and Blind Watermarking of Relational Database SystemsA. Al-Haj, A. OdehProblem statement: Digital multimedia watermarking technology was suggested in the last decade to embed copyright information in digital objects such images, audio and video. However, the increasing use of relational database systems in many real-life applications created an ever increasing need for watermarking database systems. As a result, watermarking relational database systems is now merging as a research area that … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,511 accessesView PDFCite
Research ArticleOpen accessIn the abstractImage Compression and Reconstruction using Cubic Spline Interpolation TechniqueR. Muthaiah, K. NeelaKantan, Vidur Sharma, Amit AroraA new dimension of image compression using random pixels of irregular sampling and image reconstruction using cubic-spline interpolation techniques proposed in this paper. It also covers the wide field of multimedia communication concerned with multimedia messaging (MMS) and image transfer through mobile phones and tried to find a mechanism to transfer images with minimum bandwidth requirement. This method would provide … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeparating Low Pass and High Pass Frequencies in the Image Without loosing informationZ. Alqadi, J. Musbah, A. L. MontengroGranulometries are morphological image analysis tools that are particularly useful for estimating object sizes in binary and grayscale images, or for characterizing textures based on their pattern spectra. There are many applications that morphology can be applied to. Some morphological operations like dilation, erosion and open-close are used in image and video processing, but with no application to pre-processing for … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,430 accessesView PDFCite
