Variable-rate transform coding that controls quality of image using human visual model

Abstract

This paper defines a quantitative measurement SNRq for the evaluation of image quality in the discrete cosine transform domain considering human visual characteristics. A new coding algorithm which minimizes the bit-rate for a given target SNRq also is obtained. When coding the image using the proposed algorithm, the bit-rate varies according to the image… (More)
