Motion Estimation from Scalar Dispersion in 2D Turbulent Flow

This video superimposes estimated velocity vectors on input images. Image sequence depicts the dispersion of a coloring agent in a 2D turbulent flow (courtesy of Marie-Caroline Jullien). The apparent fluid velocity motion was obtained by means of a wavelet-based optical flow. One vector every 8 pixels is displayed only.
