Abstract:

In recent years, considerable research effort has been done to optimize various digital communication channels. The significant growth of both commercial and military communication systems has emphasized the need for efficient data compression procedures. In the case of image transmission, the requirement is particularly demanding because of the significant amount of information to be transmitted. In this report, image compression procedures based on transform techniques are reviewed. The emphasis is on adaptive and, especially, on rate adaptive algorithms. The discussion includes an historical review, theoretical development, and illustrative examples of the transform image coding field. Author
