Detecting Interlaced or Progressive Source of Video
Sune Høgild Keller, Kim Steenstrup Pedersen, François Lauze · 2005
In this paper we introduce an algorithm - commonly known as a film mode detector - for separating progressive source video from interlaced source video. Due to interlacing artifacts in the presence of motion, a difference in isophote curvature can be measured and a threshold for effective classification can be set. This can be used in a video converter to ensure high quality output. We study two approaches.
