They use informations of different kinds, not only gray (or color)-level values. Here we will show how an orientation interpolation operator working in $S^1$ (angle in $[0,2\pi[$) can be used to recover geometrical information in images. The operator is presented and is used to produce fields that drive a Fast Marching contour extraction algorithm and a LIC-based smoothing method. Experiment on real images are reported to validate the proposed approach.
