Statistical modeling and simulation of rainfall in video sequences
S. Dasgupta, S. Sengupta · 2006
In this paper, we present an improved model for rainfall simulation which takes into account such fundamental and diverse factors as raindrop size, raindrop shape, viscosity and density of air, wind velocity, camera focal length, aperture time and frame size. The statistical model of the rain streaks in digital images so developed has reasonable simplifications yet remains realistic. The model is employed to generate rain-masks to add rainfall to video sequences which has interesting computer graphics applications.
