Research ArticleOpen accessEvery word in the titleImproving the Performance of Backpropagation Neural Network Algorithm for Image Compression/Decompression SystemOmaima N.A. AL-AllafProblem statement: The problem inherent to any digital image is the large amount of bandwidth required for transmission or storage. This has driven the research area of image compression to develop algorithms that compress images to lower data rates with better quality. Artificial neural networks are becoming attractive in image processing where high computational performance and parallel architectures are required. … …Journal of Computer Science, Vol. 6, Issue 11 · 26 Oct 2010 · 8,370 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAlgorithm for Compressing/Decompressing Sudoku GridsZhivko Nedev, Murtala Adamu Zungeru, Suykhun Khov et al.We describe a way to transfer efficiently Sudoku grids through the Internet. This is done by using linearization together with compression and decompression that use the information structure present in all sudoku grids. The compression and the corresponding decompression are based on the fact that in each Sudoku grid there are information dependencies and so some of the information is … …Journal of Computer Science, Vol. 16, Issue 9 · 3 Oct 2020 · 6,872 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuaternary Tree Structure as a Novel Method for Huffman Coding TreeAhsan Habib, Mohammed Jahirul Islam, Mohammad Shahidur RahmanThe binary code used by the current Huffman-based techniques slows down decoding speed. The quaternary Huffman coding method is a fresh take on the traditional Huffman coding that is suggested in this study. Each symbol is encoded into a quaternary code rather than a binary code using the quaternary Huffman coding technique. For Huffman coding, a quaternary code stream necessitates … …Journal of Computer Science, Vol. 19, Issue 9 · 24 Aug 2023 · 5,419 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSingle Core Hardware Module to Implement Partial Encryption of Compressed ImageMamun Bin Ibne Reaz, Md. Syedul Amin, Fazida Hanim Hashim, Khandaker AsaduzzamanProblem statement: Real-time secure image and video communication is challenging due to the processing time and computational requirement for encryption and decryption. In order to cope with these concerns, innovative image compression and encryption techniques are required. Approach: In this research, we have introduced partial encryption technique on compressed images and implemented the algorithm on Altera FLEX10K FPGA device that … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,379 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of String Matching Compression AlgorithmsKrishnaveny Nadarajan, Zuriati A. ZukarnainThe improvement rate in microprocessor speed by far exceeds the improvement in DRAM memory. This increasing processor-memory performance gap is the primary obstacle to improved computer system performance. As a result, the size of main memory has increased gradually. To utilize main memory’s resources effectively, data compression can be applied. Through compression, the data can be compressed by eliminating redundant … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,293 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLossless Compression Using LFSRsR. Muthiah, K. Neelakantan, Somi SebastianWhile lossy compression techniques are used for images, sound. where feature reproduction is more important than the actual data, it is necessary to use lossless compression for certain files containing data, programmes. Lossless compression techniques are not as effective as lossy ones and usually require a lot of computation for both compression and decompression. We presented a novel lossless compression … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,999 accessesView PDF Cite
