A Lagrangian Approach on Video based Fluid Animation
Haeng-A An, Jinho Park · Advanced science and technology letters · 2015
This paper proposes fluid animation method which analyzes flow field from fluid video. While current fluid animations relies on fluid simulation, this paper propose effective process which calculates 2d velocity field of smoke motion in video without fluid simulation. We utilize PCA to synthesize intermediate frames between sequential input fluid image sequences. We generate optical flow for fluid movements using a groundbreaking optical flow estimation method which is the combination of Lucas/Kanade and Horn/Schunck to achieve the best of the local and global differential methods.
