IQA of interpolated videos

Professional video editing tools can generate slow-motion video by interpolating frames from recordings at a standard frame rate. Thereby the perceptual quality of such interpolated slow-motion videos strongly depends on the underlying interpolation techniques. The Konstanz Slow Motion Video Dataset (KoSMo-1k)  is specifically tailored for interpolated slow-motion videos.

KoSMo-1k consists of 1,350 interpolated video sequences, from 30 different content sources, along with their subjective quality ratings from up to ten subjective comparisons per video pair.
