- Abstract:
-
A face detection method based on sparse granular features and the real adaptive boosting (Adaboost) meta-algorithm was proposed. A sparse granular feature set was introduced into the Adaboost learning framework. A weak look-up-table (LUT) type classifier with real confidence output was designed by extending the Bayesian stump. Then, the space of the weak classifier was constructed. The Adaboost cascade face detector was taught by using a large training set and an evaluation set. Experiments were performed on the CMU-MIT dataset, a standard public data set for benchmarking frontal face detection systems. The detection rate reached over 90% when false alarms were 20. The average processing time on a Pentium Dual1.2GHz PC was about 100 ms for a 320×240pixel image. This shows the proposed method provides good precision and speed.
