Hi all,
Given a contour (i.e. x-y points around the boundary of a shape), does anyone know how to calculate the eccentricity or even the ratio of eigenvalues of the covariance matrix of the points within the shape? The latter is simple to work out by filling the contour, but is there a method that only operates on the contour?
An example shape and eigenvalue-scaled eigenvectors α & β is shown in the attached image.
Thanks!
Doug
