An Active Appearance Model with a Derivative-Free Optimization

چکیده
A new aam matching algorithm based on a derivative free optimization is presented and evaluated in this paper. For this, we use an efficient model-based optimization algorithm, the so called newuoa algorithm from M.J.D. Powell. We compare the new matching method performances against the standard one based on a fixed Jacobian matrix learned from a training set, and show significant improvements in terms of accu-

متن کاملAn extension of stochastic differential models by using the Grunwald-Letnikov fractional derivative
Stochastic differential equations (SDEs) have been applied by engineers and economists because it can express the behavior of stochastic processes in compact expressions. In this paper, by using Grunwald-Letnikov fractional derivative, the stochastic differential model is improved. Two numerical examples are presented to show efficiency of the proposed model. A numerical optimization approach b...

متن کاملAugmented Downhill Simplex a Modified Heuristic Optimization Method
Augmented Downhill Simplex Method (ADSM) is introduced here, that is a heuristic combination of Downhill Simplex Method (DSM) with Random Search algorithm. In fact, DSM is an interpretable nonlinear local optimization method. However, it is a local exploitation algorithm; so, it can be trapped in a local minimum. In contrast, random search is a global exploration, but less efficient. Here, rand...
متن کاملAn active-set trust-region method for derivative-free nonlinear bound-constrained optimization
We consider an implementation of a recursive model-based active-set trust-region method for solving bound-constrained nonlinear non-convex optimization problems without derivatives using the technique of self-correcting geometry proposed in [24]. Considering an active-set method in modelbased optimization creates the opportunity of saving a substantial amount of function evaluations when mainta...
