Dhananjay Patel, Vinayak Bhogan, Alan Janson . Simulation and Comparison of Various Lossless Data Compression Techniques based on Compression Ratio and Processing Delay. International Journal of Computer Applications. 81, 14 ( November 2013), 31-35. DOI=10.5120/14186-2423
With increasing need to store data in lesser memory several lossless compression techniques are developed. This paper intends to provide the performance analysis of lossless compression techniques over various parameters like compression ratio, delay in processing, size of image etc. It provides the relevant data about variations in them as well as to describe the possible causes for it. It describes the basic lossless techniques as Huffman encoding, run length encoding, arithmetic encoding and Lempel-ziv-welch encoding briefly with their effectiveness under varying parameters. Considering the simulation results of grayscale image compression achieved in MATLAB software, it also focused to propose the possible reasons behind differences in comparison.
