"An Error Concealment Algorithm for Entire Frame Loss in Video Transmission"
by Yu Chen, Keman Yu, Jiang Li and Shipeng Li,
in Microsoft Research, December 2004

In video transmission over the Internet, the quality of service is usually not guaranteed. The loss of a packet may result in the loss of a whole video frame. While most of the current error concealment techniques can only deal with the loss of macro blocks, our bi-directional temporal error concealment method can recover a whole missing frame. For each pixel in the lost frame, the proposed algorithm extrapolates two motion vectors from the motion vectors of the previous reconstructed frame and the next frame. The lost pixel is then reconstructed using multi-hypothesis motion compensation. Experiments are carried the results show that our algorithm obviously outperforms the existing methods on both the PSNR and visual quality. Moreover, the proposed method is efficient in stopping error propagation.
