Detailed Description

Peak finding for noisy two-dimensional surfaces.

Operations useful in 2-dimensional peak finding. Here, peak finding works by expanding local surface patches into 2-d orthogonal polynomials of degree 2 (this is equivalent to fitting a quadratic surface using the L2 norm) and then finding the peak locations of those polynomials.
