Is there a relation between the Hessian matrix and the structure Tensor?
While the gradient contains information on the orientation, the structure tensor is a way to have an average of the orientation that respect orthogonality as it is needed to compute eigen{values|vectors … This helps to find corner by analyzing invariant of this tensor, which contain only orientation information. So if you have two high eigenvalues you are at a corner, one you are at an edge. …
