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 optimisation of the coding of uncovered regions. It is found that the widely-used tools f or coding the texture within arbitrarily shaped regions of the intra i mage are not appropriate for failure regions. A new method for doing s o is proposed which consists of applying a predictive coding step to t he newly visible portions based on already transmitted spatial data.
