Abstract
The invention is related to decoding of block wise coded video pictures. The determination of using de-blocking filtering between coded blocks is based on alternative characteristics compared to the characteristics used in H.264/AVC.
Claims3
A method in video decoding for reducing blocking artifacts between a first and a second block in a block wise coded video picture by performing a first test of adjacent blocks and a second test of pixel lines crossing a boundary and/or an extension of the boundary between the first and the second block and executing a de-blocking filter operation on boundary neighboring pixels if the test indicates artifacts, characterized in performing the second test on a subset of the pixel lines only, and if the test indicates artifacts, executing a de-blocking filter operation on the boundary neighboring pixels in each of the pixel lines crossing the boundary.
