Particle Swarm Optimization based Adaboost for face detection

This paper proposes a PSOAdaBoost algorithm incorporating particle swarm optimization within an AdaBoost framework for face detection applications. The basic component of an AdaBoost detector is a weak classifier, consisting of a feature, selected by an exhaustive search mechanism, and a decision threshold. The proposed PSOAdaBoost computes the best feature and optimizes the threshold in one optimization process. Experiments between the proposed algorithm and AdaBoost (with exhaustive feature selection) suggest that PSOAdaBoost has better performance in terms of much less training time and better classification accuracy.
