Realistic video rain editing
Lizhuang Ma · Computer Engineering and Applications Journal · 2009
Realistic rain rendering is a hot topic in the movie industry.It is usually simulated by particle system,which acquires a large number of particles with complex physical models to render photo-realistic rain.This paper proposes a new method to render photo-realistic rain by image based methods.This paper segments the realistic rain from video by minimal value filter and improves Matting algorithm.Then merge them into a new scene after translating their color style by different light condition.Experiments show the method is effective.Because of the method operates on the video image,it avoids the expensive 3D scene modeling.It is suitable for low cost movie maker and the video material reuse field.
