Comparison of GVF, NGVF, and EDNGVF vector fields. (a) From left to right: GVF force field; magnified GVF field at concave region and stationary point in GVF. (b) From left to right: the NGVF force field; magnified NGVF field at concave region and the saddle and stationary points in NGVF. (c) From left to right: the EDNGVF force field; magnified force field in concave region.
