Abstract
A method, apparatus, and computer program product provide for improving parameter selection decisions in hybrid video and image codecs. In the context of a method, the method generates a block of difference samples based on a difference between a first block of samples and a second block of samples. The method also generates a block of transform coefficients by applying a transformation process to the block of difference samples. The method also determines an absolute value for each transform coefficient in the block of transform coefficients and determines a weighted sum value for all absolute values of the transform coefficients within the block of transform coefficients. The method also applies the weighted sum value as a criterion for a selection decision.
