Paper Abstract

Wavelet theory provides an alternative approach to traditional DCT-based coding with properties that suggest an advantage over traditional schemes, especially for high compression ratios. This paper presents the design of an image coder for very low bit rates (8..64 kbit/s) which can be used for videophone applications. Apart from the image quality coding delay is an important critical factor. The coder performs a hybrid motion compensation/transform coding approach using a warping motion compensation to completely avoid blocking artifacts. Experiments using standard videophone test sequences show that the obtained image quality is similar to the best available results from DCT coders.
