Improvements to a temporal filter for video coding

This paper presents improvements to the original motion compensated temporal pre-filter implemented in the VVC reference model VTM and the HEVC reference model HM. The improvements involve motion estimation modifications, increasing the number of neighboring pictures to use, and filtering strength w...

description This paper presents improvements to the original motion compensated temporal pre-filter implemented in the VVC reference model VTM and the HEVC reference model HM. The improvements involve motion estimation modifications, increasing the number of neighboring pictures to use, and filtering strength weighting depending on block error metrics. Results are presented on VTM-14.0. Tested content includes JVET common conditions test set, sequences with introduced fading and scene cuts, and additional 4:2:2 and 4:4:4 chroma format test sequences.
