Symbol positions‐based Slepian–Wolf coding with application to distributed video coding

Distributed Coding of Endoscopic Video Distributed Coding of Endoscopic Video

Triggered by the challenging prerequisites of wireless capsule endoscopic video technology, this paper presents a novel distributed video coding (DVC) scheme, which employs an original hash-based side-information creation method at the decoder. In contrast to existing DVC schemes, the proposed codec generates high quality side-information at the decoder, even under the strenuous motion conditio...

Distributed Video Coding with Geometric Transforms

Abstract The Distributed Video Coding (DVC) paradigm is based on two well-known information theory results: the SlepianWolf and the Wyner-Ziv theorems. In a DVC codec, the correlation between video signals is exploited at the decoder, providing a flexible distribution of the computational complexity between the encoder and the decoder and error robustness to the channel errors. To exploit the c...

Distributed video coding with progressive significance map

A distributed video coding (DVC) system based on wavelet transform and set partition coding (SPC) is presented in this paper. Conventionally the significance map (sig-map) of SPC is not conducive to Slepian-Wolf (SW) coding, because of the difficulty of generating a side information sig-map and the sensitivity to decoding errors. The proposed DVC system utilizes a higher structured significance...

In this paper, we propose a perceptual-based distributed video coding (DVC) technique. Unlike traditional video codecs, DVC applies video prediction process at the decoder side using previously received frames. The predicted video frames (...
