Spatio-temporal correlation-variational approach for robust optical flow estimation

Estimation robuste du flot optique par approche spatio-temporelle combinant corrélation et méthode variationnelle

Résumé

We present in this paper a novel collaborative scheme dedicated to the measurement of velocity in fluid experimental flows through image sequences. The proposed technique combine the robustness of correlation techniques with the high density of global variational methods. It can be considered either as a reenforcement of fluid dedicated optical-flow methods towards robustness, or as an enhancement of correlation approachs towards dense information. This results in a technique that is robust under noise and outliers, while providing a dense motion field. The method was applied on synthetic images and on real experiments in turbulent flows carried out to allow a thorough comparison with a state of the art optical-flow and PIV methods.
