Face detection based on adaboost and face contour in e-learning
Wansen Wang, Yaya Peng · 2013
The background of this paper is the learners' expression recognition in E-learning. In the paper, the method of the face detection based on the adaboost algorithm and a set of haar wavelet like features. To improve the performance of the detectors, the face-contour is combined with the adaboost. The experimental results demonstrate that it can find the position of the detected faces of learners in E-learning accurately.
