Research ArticleOpen accessIn the abstractA New Algorithm for Fractal Coding Using Self Organizing MapS. Bhavani, k. ThanushkodiProblem statement: In medical imaging, lossy compression schemes are generally not used due to possible loss of useful clinical information and also degradations may result in lossy compression owing to operations like enhancement. As the medical images are huge in size a good lossy compression technology is required to store them in medical archives in an economical manner. There is … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 7,583 accessesView PDFCite
Research ArticleOpen accessIn the abstractStill Image Compression Using Texture and Non Texture Prediction ModelG. Mohanbaabu, P. RenugaProblem statement: Existing lossless image compression schemes attempt to do prediction in an image data using their Local Binary Pattern (LBP) and their spatial neighborhood based techniques. In the previous techniques such as Vector Quantization (VQ) and Gradient Adjusted Prediction (GAP) the texture and non-texture regions are not classified separately. Texture and Non-texture images prophecy has been a key factor … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 11 Feb 2012 · 7,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Programmable Gate Arrays Based Realization of Truncated MultipliersMuhammad H. Rais, Mohammed H. Al MijalliProblem statement: Due to high cost and non reconfiguration of Application Specific Integrated Circuits (ASICs) in image processing applications, for example MPEG video compression used in CT scan frames requires real time conditions and the algorithms should be verified and optimized before implementation. Approach: Field Programmable Gate Array (FPGA) provides reconfiguration and implementation at the same time. Results: The implementation … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 6,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpartan-3AN Field Programmable Gate Arrays Truncated Multipliers Delay StudyMohammed H. Al MijalliProblem statement: The image processing applications, such as MPEG video compression used in CT scan frames requires real time conditions and the algorithms should be verified and optimized before implementation which cannot be done with Application Specific Integrated Circuits (ASICs) because they are not reconfigurable and cost is very high. Approach: The FPGA is a viable technology that could be … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,428 accessesView PDFCite
