Claim One:
1. A method for reducing blocking artifacts at the boundary between adjacent blocks reconstructed from a frame of compressed video information that includes a prediction stage parameter with respect to at least one of the blocks, the method comprising: reconstructing the at least one block based on the prediction stage parameter; computing a residual error attribute from the reconstructed block; categorizing the at least one block into one of a plurality of categories based on at least one of the prediction stage parameter or the residual error attribute; identifying one or more filter modifiers for the category in which the at least one block is categorized based on at least one of the prediction stage parameter or the residual error attribute associated with that category; computing a filter strength value based on a baseline filter strength and, the identified one or more filter modifiers; and filtering the boundary adjacent to the at least one block using the selected computed filter strength value.
