Through comparing calculation with typical examples, it shows that the question of localminimization can be avoided effectively using the improved algorithm, so the method has practicability.

Because the proposed angular feature is invariant to rotation, translation and scale transformation, the registration result will converge to global minimization rather than local one.
We use the theory of local risk minimization for incomplete markets to determine hedging strategies for equity-linked life insurance contracts with stochastic interest rates.
