lye propose a lossy image coding scheme based on the recently introduced even-stacked cosine modulated filter banks (CSIFBs) that allow linear phase filters in all channels. We des...

This paper contains two contributions to very-low-bitrate video coding. First, we show that in contrast to common practice incremental techniques for rate-distortion optimization ...
