Planimetric control. Segmentation is sometimes a ground step for correlation which approximates regions by plans, thus we have studied a way to control in 2D the planimetric differences between a reference and a segmentation outline. Various distances have been used for this purpose : Haussdorf distance from segmentation boundaries to reference ones seem to be the most appropriate. A recovering surface quality estimator has been tried and we have computed the ratio between intersection and union with respect to the both areas.
