MD-VQA: Multi-Dimensional No-Reference Video Quality Assessment for CVPR NTIRE 2023
Alibaba’s Taobao VQA team won the CVPR NTIRE 2023 Video Enhancement Challenge by introducing MD‑VQA, a multi‑dimensional no‑reference video quality model that combines a Swin‑Transformer‑V2 spatial backbone, a pre‑trained SlowFast motion encoder, and a convolutional fusion module, pre‑trained on LSVQ, fine‑tuned on NTIRE data, and augmented spatio‑temporally, achieving state‑of‑the‑art SROCC and PLCC scores and now powering quality monitoring on Alibaba’s live‑streaming and short‑video services.
