C13. A novel error concealment technique for wavelet-coded I-frames for block-based video coding systems

In video communication over lossy packet networks (e.g., the Internet), packet loss errors can severely damage the transmitted video. The damaged video can largely be repaired with spatial error concealment, where neighboring information was used to estimate missing information. They mask the effect of missing blocks by using the spatial or/and temporal correlation to create image or video of subjectively acceptable quality.
