Dense estimation of fluid flows

Dense Estimation of Fluid Flows

ÐIn this paper, we address the problem of estimating and analyzing the motion of fluids in image sequences. Due to the great deal of spatial and temporal distortions that intensity patterns exhibit in images of fluids, the standard techniques from Computer Vision, originally designed for quasi-rigid motions with stable salient features, are not well adapted in this context. We thus investigate ...

Dense Fluid Flow Estimation

In this paper we address the problem of estimating and analyzing the motion in image sequences showing uid phenomenon. Due to the great deal of spatial and temporal distortions that luminance patterns exhibit in images of uid, standard techniques from Computer Vision, originally designed for quasi-rigid motions with stable salient features, are not well adapted in this context. In that prospect...

Motion Estimation Based on a Temporal Model of Fluid Flows

In algorithmic fluid flow estimation, regularization of neighboring flow vectors has become an important approach employing prior knowledge on resulting flow fields. Up to now, the main focus has been spatial regularization by means of either analytic terms or parametric models. In this paper we propose a new method for estimating flow fields using parametric models of temporal trajectories, wh...
