A Detection Strategy of Multi-Pose Face in Compressed Domain

摘要

In this paper, we present a strategy lo implement multi-pose face detection in compressed domain. The strategy extracts firstly feature vectors from DCT domain, and then uses a boosting algorithm to build classifiers to distinguish faces and non-faces. Moreover, to get more accurate results of the face detection, we present a kernel function and a linear combination to build incrementally the strong classifiers based on the weak classifiers. Through comparing and analyzing results of some experimentson the synthetic data and the natural data, we can get more satisfied results by the strong classifiers than by the weak classifies.
