In this survey, we give an overview of invariant interest point detectors, how they evolved over time, how they work, and what their respective strengths and weaknesses are. We begin with defining the properties of the ideal local feature detector. T
Gaussian curvature is an isometric invariant of a surface. An isometric invariant is a surface property that depends only on the E, F, G functions(and possibly their derivatives).
