Research ArticleOpen accessIn the keywordsAnalysis 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 abstractDiscrete Shearlet Transform and Lempel-Ziv Welch Coding for Lossless Fingerprint Image CompressionNahidah A. Kadim, Shawkat K. Guirguis, Hend A. ElsayedImage compression is a crucial task in image processing and in the process of sending and receiving files. There is a need for effective techniques for image compression as the raw images require large amounts of disk space to defect during transportation and storage operations. The most important objective of image compression is to decrease the redundancy of the image … …Journal of Computer Science, Vol. 20, Issue 5 · 5 Mar 2024 · 5,485 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPERFORMANCE COMPARISON OF HUFFMAN AND LEMPEL-ZIV WELCH DATA COMPRESSION FOR WIRELESS SENSOR NODE APPLICATIONAsral Bahari Jambek, Nor Alina KhairiWireless Sensor Networks (WSNs) are becoming important in today’s technology in helping monitoring our surrounding environment. However, wireless sensor nodes are powered by limited energy supply. To extend the lifetime of the device, energy consumption must be reduced. Data transmission is known to consume the largest amount of energy in a sensor node. Thus, one method to reduce the energy … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,942 accessesView PDF Cite
