摘要：
The AV1 deblocking filter did not sufficiently attenuate visual quality artifacts when used in the AOMedia video model (AVM), especially at lower bitrates. A generalized deblocking filter described in this paper uses one equation for any filter length. The filter brings PSNR-YUV BD-rate -0.17%, -0.90%, -1.07%, and -0.92% on All Intra, Random Access, Low-Delay, and Adaptive Streaming configurations in the AOMedia common test conditions. Improvement of visual quality is observed on a number of sequences, while the computational complexity is close to that of the AVM deblocking.
