Evaluation of lossless compression techniques

Growth of Internet and explosive development of mobile communications has given high demand to multimedia applications. Data explosion and the need for real time processing has resulted in requirements like large disk space and reduced transmission time. These key requirements have given rise to data compression technology. Data compression is a science of representing information in a compact form. The key factor in compression is to remove redundancy of data present within a data set in order to reduce its size without affecting the essential content in it. Lossless compression format is basically defined by characteristics such as bit rate, PSNR etc. This paper is an effort to evaluate different lossless compression techniques available which are used in applications where integrity of the data is maintained with high quality.
