Multidimensional Adaptive Non-linear Filters for Concealment of Interlaced Video
نویسندگان
چکیده
The application of multidimensional adaptive non-linear filters for interpolation of interlaced imagery is investigated. Moreover, a new scheme for combination of several data estimates by weighting based on one-sample correlation is proposed. This technique achieves superior performance when combining vertical and temporal signals at a moderate complexity increase. In the spatial domain, one-dimensional non-adaptive Lagrange interpolators are found to provide sufficient objective and subjective image quality as compared to two-dimensional linear and non-linear filters, and median-type filters.

An Efficient Adaptive Boundary Matching Algorithm for Video Error Concealment
Sending compressed video data in error-prone environments (like the Internet and wireless networks) might cause data degradation. Error concealment techniques try to conceal the received data in the decoder side. In this paper, an adaptive boundary matching algorithm is presented for recovering the damaged motion vectors (MVs). This algorithm uses an outer boundary matching or directional tempo...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
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 کاملUtilizing Kernel Adaptive Filters for Speech Enhancement within the ALE Framework
Performance of the linear models, widely used within the framework of adaptive line enhancement (ALE), deteriorates dramatically in the presence of non-Gaussian noises. On the other hand, adaptive implementation of nonlinear models, e.g. the Volterra filters, suffers from the severe problems of large number of parameters and slow convergence. Nonetheless, kernel methods are emerging solutions t...
متن کاملRecent developments in multidimensional multirate systems
Multidimensional (MD) multirake systems, which find applications in the coding and compression of image and video data, have recently attracted much attention. The basic building blocks in an MD multirate system itre the decimation matrix M, the expansion matrix L, and MD digital filters. With D denoting the number of dimensions, M :and L are D X D nonsingular integer matrices. When these matri...
