Data transmission, storage and processing are the integral parts of today's information systems. Transmission and storage of huge volume of data is a critical task in spite of the advancements in the integrated circuit technology and communication. In order to store and transmit such a data as it is, requires larger memory and increased bandwidth utilization. This in turn increases the hardware and transmission cost. Hence, before storage or transmission the size of data has to be reduced without affecting the information content of the data.
