Paper Abstract

Techniques for full scalability with motion-compensated temporal filtering (MCTF) in the wavelet-domain (in-band) are presented in this paper. The application of MCTF in the wavelet domain is performed after the production of the overcomplete discrete wavelet transform from the critically-sampled decomposition, a process that occurs at both the encoder and decoder side. This process, which is a complete-to-overcomplete discrete wavelet transform, is critical for the efficiency of the system with respect to scalability, coding performance and complexity. We analyze these aspects of the system and set the necessary constraints for drift-free video coding with in-band MCTF. As a result, the proposed architecture permits the independent operation of MCTF within different resolution levels or even different subbands of the transform and allows the successive refinement of the video information in resolution, frame-rate and quality.
