Expand description
Saddle-point quadratic-surface refiner.
Fits a 2nd-order surface I(x, y) = a x² + b x y + c y² + d x + e y + f
to the image patch around the seed and locates the unique
stationary point of the resulting quadratic. The Hessian
[2a b; b 2c] must have negative determinant (a saddle) for the
corner to be accepted.
