Motion-keying Based Dynamical Scene Layering with Adaptive Learning
Charles Z. Liu, Manolya Kavakli, Scott McCallum, Len Hamey · 2017
Chroma-keying has been widely applied in multimedia. However, its constraints, including stadium setup, mono-chroma detection and specific techniques for video capture, limit the utilization in consumer electronic applications. This paper presents an economical scheme to perform the keying effect based on motion tracking with low requirements on the conditions for keying. An adaptive learning strategy is also developed to perform a layering task without the support of prior knowledge of the scene. An example is given to demonstrate the effect.
