Which is simple if I want to calculate surface curvature.
By reading this:
The principal curvature values and the principle directions of the curvatures are calculated by taking the eigenvalue decomposition of the Hessian Matrix which is defined as:
Using principal curvatures, Mean (H) and Gaussian (K) Curvatures are calculated as:
H = (K 1 +K 2 )/ 2 , K =k1 ⋅k 2
(2) method is:
Which is easy to calculate in matlab?
