Code for paper "StableVQA: A Deep No-Reference Quality Assessment Model for Video Stability" (Accepted by ACM MM'23)

We propose StableVQA for accurate prediction of video stability. Flow Feature: After sampling N frames from the video clip, the optical flows between adjacent frames are estimated and are taken as input to a 3D CNN to implicitly analyze the camera movement. Semantic feature: We use a Swin-T for the extraction of semantic features. Blur Feature: We analyze the motion blur effect within frames. Features from three dimensions are fused and regressed to give the final prediction stability score.
