Abstract [en]

We have developed a statistical prediction technique to compensate for lost pixel blocks during real time transmission of video over packet-switched networks. The approach could as well be used for standard inter-frame coding. The method is based on the joint modeling of pixel statistics by Gaussian mixtures. Different EM variants for decreasing computational complexity and storage space are proposed. In the case of 4×4 luminance blocks, ourmethod increases performance by 2.3 dB when augmenting the number of mixture components from 1 to 64. We show that these results are statistically significant.
