Interframe texture coding of uncovered regions for a region-based scheme

Region-based coding schemes for video sequences have recently received much attention owing to their potential to enable several interesting multimedia applications. The authors focus on the optimization of the coding of uncovered regions. It is found that the widely-used tools for coding the texture within arbitrarily shaped regions of the intra-image are not appropriate for failure regions. A new method for doing so is proposed which consists of applying a predictive coding step to the newly visible portions based on already transmitted spatial data.
