On edge detection
V. Torre,Tomaso Poggio +1 more
TL;DR: It is shown that numerical differentiation of images is an ill-posed problem in the sense of Hadamard, and that this part of edge detection consists of two steps, a filtering step and a differentiation step.

Geometric bounds on the density of resonances for semiclassical problems
TL;DR: In this article, the authors give upper bounds on the number of resonances in certain regions in the complex plane close to the real axis for semiclassical operators like −h 2 Δ+V(x) when h is small.
