This thesis is concerned with fluid motion analysis in image sequences and involves two main issues. In a first part, we address the problem of estimating a dense motion field. Due to the great deal of spatial and temporal distortions that luminance patterns exhibit in fluid imagery, standard techniques from Computer Vision, originally designed for quasi-rigid motions with stable salient features, are not well adapted. In that prospect, we investigate a dedicated energy-based motion estimator. The considered functional includes an original data model relying on the continuity equation of fluid mechanics. This new data model, which is specifically designed to be embedded in a multiresolution framework, is associated to an original ``div-curl...
