I wasn't really sure how to estimate the second derivates and if it would give any useful information, so instead I fit constrained multivariate Gaussians (only fit the diagonal parameters of the covariance matrix using least squares) around each of the minima/maxima that should tell us how the data behaves around the extrema.
