New Hybrid Error Concealment for Digital Compressed Video
EURASIP Journal on Advances in Signal Processing, 2005 Transmission of a compressed video signal over a lossy communication network exposes the information to losses and errors, which leads to significant visible errors in the reconstructed frames at the decoder side.

Error Concealment for Frame Losses in MDC [PDF]
IEEE Transactions on Multimedia, 2008 Multiple description coding (MDC) is an effective error resilience (ER) technique for video coding. In case of frame loss, error concealment (EC) techniques can be used in MDC to reconstruct the lost frame, with error, from which subsequent frames can be decoded directly.

Error concealment using motion field interpolation [PDF]
, 1998 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

Error concealment for slice group based multiple description video coding [PDF]
, 2005 This paper develops error concealment methods for multiple description video coding (MDC) in order to adapt to error prone packet networks. The three-loop slice group MDC approach of D. Wang et al. (2005) is used.

Optimized temporal error concealment through evaluation of multiple concealment features [PDF]
, 2006 In this paper we formulate an optimized temporal error concealment approach for H.264 based on the study of the performance of several temporal concealment features that apply to the different steps of the proposed method.

Image Error Concealment Based on Deep Neural Network
Algorithms, 2019 In this paper, we propose a novel spatial image error concealment (EC) method based on deep neural network. Considering that the natural images have local correlation and non-local self-similarity, we use the local information to predict the missing ...
