Application of vector rational interpolation to erroneous motion field estimation of error concealment
نویسندگان
چکیده
A study on the use of vector rational interpolation for the estimation of lost or erroneously received motion vectors of MPEG-2 coded video bitstreams for error concealment purposes is reported. Four different nonlinear interpolation schemes are examined. They are capable of adapting their behaviour to neighbouring motion information. Simulation results prove the success of their application to concealment of predictively coded frames. Such concealment is fast and thus adequate for real-time applications.

Motion field estimation by vector rational interpolation for error concealment purposes
A study on the use of vector rational interpolation for the estimation of erroneously received motion fields of an MPEG-2 coded video bitstream has been performed. Four different motion vector interpolation schemes have been examined using motion information from available top and bottom adjacent blocks since left or right neighbours are usually lost. The presented interpolation schemes are cap...
متن کاملAn Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis
In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
متن کاملError Concealment using Motion Field Interpolation
In the context of block-based video coding, two error concealment algorithms are presented. The first algorithm is based on bilinear motion field interpolation (BMFI). For each pel in a damaged block, the algorithm recovers a motion vector using bilinear interpolation of neighbouring motion vectors. This vector is then used to conceal the damaged pel. A reduced complexity version of this algori...
متن کاملA Temporal Error Concealment Algorithm for H.264 Based on Plane Estimation
In this paper, we propose a new temporal error concealment algorithm for the forthcoming video coding standard H.264, which uses a first-order plane to estimate motion vector. In H.264, a 16 16 inter macroblok can be divided into variant block shape for motion prediction. The blocks within a small area are likely to move in the same direction. By using the motion vectors that next to the vertic...
متن کاملSpatio-temporal video error concealment with perceptually optimized mode selection
We propose a spatio-temporal error concealment algorithm for video transmission in an error-prone environment. The proposed technique employs motion vector estimation, edge-preserving interpolation, and texture analysis/synthesis. It has two main advantages with respect to existing methods, namely i) it aims at optimizing the visual quality of the restored video, and not only PSNR, and ii) it e...
