| Abstract: | This article describes the implementation of a simple wavelet-basedoptical-flow motion estimator dedicated to continuous motions such asfluid flows. The wavelet representation of the unknown velocity field isconsidered. This scale-space representation, associated to a simplegradient-based optimization algorithm, sets up a well-defined multiresolutionframework for the optical flow estimation. Moreover, a very simple closuremechanism, approaching locally the solution by high-order polynomials isprovided by truncating the wavelet basis at fine scales. Accuracy and efficiencyof the proposed method are evaluated on image sequences of turbulent fluid flows. |
