Abstract

Zooming and zero padding interpolation algorithms based on the conventional discrete cosine transform (DCT) are presented. The DCT algorithms are shown to be more accurate and outperform algorithms based on the Wang modified DCT-I which was proposed to replace the DCT for interpolation purposes.
