Abstract
A method for estimating blockiness in a video frame of transform-based video encoding includes: obtaining a bitstream of a transform coded video signal, the signal being partitioned into video frames and all operations being performed on a per frame basis, wherein coefficients constituting transforms encoded in the bitstream of the video frames are read; averaging the coefficients of the transforms encoded in the bitstream into one averaged transform matrix per transform block size i; generating or making available one weighting matrix per averaged transform of block size i; computing intermediate weighted average transform matrices; processing all members of each weighted and averaged transform matrix into a single value per transform of block size i, to obtain intermediate signals; and computing a single value by weighting values of the intermediate signals according to an area in the respective video frame and adding up the weighted values of the intermediate signals.
