LeviCivitaTensor[d] gives the d-dimensional Levi-Civita totally antisymmetric tensor.
MaxFilter[image, r] filters image by replacing every value by the maximum in its range r neighborhood. MaxFilter[data, r] applies max filtering to an array of data.
MinFilter[image, r] filters image by replacing every value by the minimum in its range r neighborhood. MinFilter[data, r] applies min filtering to an array of data.
MorphologicalPerimeter[image] picks out the morphological perimeter of regions of foreground in image.MorphologicalPerimeter[image, t] treats values above t as foreground.
