Paper Abstract

An adaptive cosine transform coding scheme capable of real-time operation is described. It incorporates the human visual system properties into the coding scheme. Results showed that the subjective quality of the processed images is significantly improved even at a low bit rate of 0.2 bit/pixel. With the adaptive scheme, an average of 0.26 bix/pixel can be achieved with very little perceivable degragation.
