An efficient hybrid distributed video coding
نویسندگان
چکیده
An efficient hybrid distributed video coding (HDVC) scheme combining residual coding, SW-SPIHT coding and intra-mode decision technology is proposed to offer good rate-distortion performance and low-complexity encoding. The scheme adopts the waveletdomain Wyner-Ziv codec to compress the residual frame between the current frame and its reference frame. An intra-mode decision based on the temporal and spatial correlation is made to determine whether a wavelet block is better coded or not. When the estimated correlation is weak, we use intra-SPIHT coding; otherwise SW-SPIHT (Slepian-Wolf SPIHT) coding is adopted. Experimental results indicate the proposed HDVC achieves evident improvement than the referenced.

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard
Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملA Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding
Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...
متن کاملAnalysis and application of turbo coder based distributed video coding
This work investigates a Distributed Video Coding (DVC) method for single view video sources. DVC is different from hybrid block-based video coding as there is no temporal prediction included in the encoding process. This makes video codecs with low encoder workload possible. DVC in this thesis is an extension of source coding with side information, a subset of Slepian-Wolf coding. The theoreti...
متن کاملDynamic Complexity Coding: Combining Predictive and Distributed Video Coding
In this paper a new video coding paradigm called dynamic complexity coding is presented. It combines conventional predictive coding techniques and distributed video coding concepts to create a codec that is able to adapt to the possibly varying complexity constraints imposed on both encoder and decoder. The main idea is to share the complex motion estimation computations in a dynamic way: if th...
