abstract = {<p style="text-align: justify;">This article describes the implementation of a simple wavelet-based
optical-flow motion estimator dedicated to continuous motions such as
fluid flows. The wavelet representation of the unknown velocity field is
considered. This scale-space representation, associated to a simple
gradient-based optimization algorithm, sets up a well-defined multiresolution
framework for the optical flow estimation. Moreover, a very simple closure
mechanism, approaching locally the solution by high-order polynomials is
provided by truncating the wavelet basis at fine scales. Accuracy and efficiency
of the proposed method are evaluated on image sequences of turbulent fluid flows.</p>},
