Abstract
A method and apparatus for identifying a prediction block which generates smooth residuals in block motion compensated transform-based video coders. A base block from a first image, and a candidate prediction block from a second image, are selected. A differential block is generated using the candidate prediction block and the base block. The differential block is passed through a filter. A total energy value for the filtered block is measured, and used for determining whether the candidate prediction block is selected.
