  In this paper, we propose a quality enhancement network of versatile video
coding (VVC) compressed videos by jointly exploiting spatial details and
temporal structure (SDTS). The proposed network consists of a temporal
structure fusion subnet and a spatial detail enhancement subnet. The former
subnet is used to estimate and compensate the temporal motion across frames,
and the latter subnet is used to reduce the compression artifacts and enhance
the reconstruction quality of compressed video. Experimental results
demonstrate the effectiveness of our SDTS-based method.
