摘要
En 中文
The demand for high-speed transmission of best quality images over the internet has led to a strong need for the development of better algorithm for coding images. The transform coders are highly popular in encoding images. M-dimensional real transform (MRT) gives an alternate representation of a signal in the frequency domain which involves only real addition. In this paper a new transform coder based on 4 x 4 MRT is proposed and its performance is analyzed for all types of grayscale images. (c) 2007 Elsevier GmbH. All rights reserved.
