A Pixel Domain Video Coding based on Turbo code and Arithmetic code
نویسندگان
چکیده
In recent years, with emerging applications such as multimedia sensors networks, wireless low-power surveillance and mobile camera phones, the traditional video coding architecture in being challenged. In fact, these applications have different requirements than those of the broadcast video delivery systems: a low power consumption at the encoder side is essential. In this context, we propose a pixel-domain video coding scheme which fits well in these senarios. In this system, both the arithmetic and turbo codes are used to encode the video sequence's frames. Simulations results show significant gains over Pixel-domain Wyner-Ziv video codeingr.

Low-complexity feedback-channel-free distributed video coding using local rank transform
In this paper, we propose a new feedback-channel-free Distributed Video Coding (DVC) algorithm using Local Rank Transform (LRT). The encoder computes LRT by considering selected neighborhood pixels of Wyner-Ziv frame. The ranks from the modified LRT are merged, and their positions are entropy coded and sent to the decoder. In addition, means of each block of WynerZiv frame are also transmitted ...
متن کاملVideo Abstraction in H.264/AVC Compressed Domain
Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...
متن کاملENTROPY OF GEODESIC FLOWS ON SUBSPACES OF HECKE SURFACE WITH ARITHMETIC CODE
There are dierent ways to code the geodesic flows on surfaces with negative curvature. Such code spaces give a useful tool to verify the dynamical properties of geodesic flows. Here we consider special subspaces of geodesic flows on Hecke surface whose arithmetic codings varies on a set with innite alphabet. Then we will compare the topological complexity of them by computing their topological ...
متن کاملEnabling Error-Resilient Internet Broadcasting using Motion Compensated Spatial Partitioning and Packet FEC for the Dirac Video Codec
Video transmission over the wireless or wired network require protection from channel errors since compressed video bitstreams are very sensitive to transmission errors because of the use of predictive coding and variable length coding. In this paper, a simple, low complexity and patent free error-resilient coding is proposed. It is based upon the idea of using spatial partitioning on the motio...
متن کاملDistributed Video Coding Based on Selective Data Pruning and High-order Edge-directed Interpolation
In the current distributed video coding (DVC), a low resolution video sequence is generated with spatial and/or temporal downsampling at the encoder. At the decoder side, interpolation is performed and the interpolated pixels are further refined by using a error-correcting code such as Turbo codes or LDPC. In our previous work, we proposed a spatial domain DVC which uses a line-based downsampli...
