An Active Appearance Model with a Derivative-Free Optimization
IAPR International Workshop on Machine Vision Applications
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 accuracy.dblp:conf/mva/ZhangDP09 fatcat:5kpfqz4mezbmpjnzg6reaymqfe
