ABSTRACT:
A system and method for improving prediction error coding performance of various video compression algorithms. Various embodiments combine the energy compaction features of transform coding with localization properties of spatial coding. In various embodiments, the effects of pixel “outliers” are removed from the transform and are coded separately as a spatially coded pixel prediction, thereby improving the coding gain of the transform.
