A Review on Lossless Image Compression Techniques

Compression is a technique to reduce the quantity of data without excessively reducing the quality of the data. Image compression is the application of data compression on digital images. Image compression is used to minimize the amount of memory needed to represent an image, for storage or transmission of information. When hearing that image data are reduced, one could expect that automatically also the image quality will be reduced. A loss of information is, however, totally avoided in lossless compression, where image data are reduced while image information is totally preserved.TV and fax machines are both examples of image transmission and digital video player is the example of image storage. In this paper we review and discuss about the Image, different types of Image formats, Lossless image compression, need of lossless compression, its principles, benefits, performance measures and various techniques of lossless image compression.
