This document is the final report on the evaluation of the tasks of the workpackage 2. It gives results of the statistical evaluation of 2D/3D turbulent shear flows estimations with optical flow approaches, developed within workpackage 2 of the project FLUID. Three approaches are evaluated: OF1, a variational fluid dedicated optical flow estimator (Corpetti et al., 2006); OF2, a variational motion estimator for incompressible flows (Yuan et al., 2007); COROF1, a collaborative correlation - variational approach for robust optical flow estimation (Héas et al., 2007; Heitz et al., 2007).
