Crosscheck of JVET-O0532 (Non-CE5: Simplification on clipping value calculation for adaptive loop filter)
Authors: K. Unno KDDI
Abstract
It is reported that cross-check results of JVET-O0532. The cross checker reports that the source code provided by Qualcomm who proposes JVET-O0532 has been analysed and has been found to be consistent with the description in JVET-O0532. In JVET-O0532, it is tested that alternative definitions of the clipping thresholds for the Non-Linear ALF. There are 3 sub-tests in JVET-O0532. The method 1 changes the definition of the clipping thresholds from power of 2 to bit-shifts. In the method 2 and 3, fixed values are used instead of the values calculated in the method 1 and the current VVC design. The cross checker could reproduce the results reported in JVET-O0532. The difference from measured encoder and decoder run time ratios to those reported in JVET-O0532 is acceptable.
