Efficient Multiple-Description Image Coding Using Directional Lifting-Based Transform
This paper proposes an efficient two-description image coding technique. The two side descriptions of an image are generated by quincunx subsampling. The decoding from any side des...

Directional Lifting-Based Wavelet Transform for Multiple Description Image Coding with Quincunx Segmentation
In this paper, a new multiple description image coding scheme using directional lifting transform is proposed. The basic idea is to divide an image into two descriptions with quinc...
