Abstract: In this work, a new method to deal with the unconnected pixels in motion compensated temporal filtering (MCTF) is presented, which is designed to improve the performance of 3D lifted wavelet coding. Furthermore, multiple description scalable coding (MDSC) is investigated, and novel MDSC schemes based on 3D wavelet coding are proposed, using the lifting imple- mentation of temporal filtering. The proposed MDSC schemes can avoid the mismatch problem in multiple description video coding, and have high scalability and robustness of video transmission. Experimental results showed that the proposed schemes are feasible and adequately effective.

Robust video transmission based on distributed multiple description coding

- 03 Sep 2007
TL;DR: This paper proposes systematic lossy description coding for robust video transmission over error-prone channels by first structuring the data to be encoded into two descriptions, and extended to the use of motion-compensated temporal filtering for the Wyner-Ziv frames, in which case only the low-frequency subbands are WZ-coded and sent in the descriptions.

TL;DR: A joint source-channel coding scheme using motion-compensated oversampled filterbanks (OFB) and the redundancy introduced by the overcomplete representation is employed for error correction of the motion compensated frames.
DDWT-layer-based multiple description video coding

TL;DR: The proposed method can achieve higher coding performance since it not only makes good use of the rich directional selectivity of DDWT and the correlation between four wavelet trees, but also compensates the lack of the horizontal and vertical direction selectivity in DDWT.

Multiple-description video coding using motion-compensated temporal prediction
TL;DR: This work proposes multiple description (MD) video coders which use motion-compensated predictions and provides three different algorithms to control the mismatch between the prediction loops at the encoder and decoder.

TL;DR: The results indicate that the proposed methods offer improvements over similar competing methods by up to 1 dB for images, and several decibels for video, and Visual quality is also improved.

- 07 May 2001
TL;DR: The lifting formalism allows us to provide several improvements to the scheme initially proposed by Choi and Woods: a better processing of the uncovered areas is proposed and an overlapped motion-compensated temporal filtering method is introduced in the multiresolution decomposition.
