At present, feature-based classification method is widely used in video surveillance system. How to find a group of features which are stable and efficient is concerned by researchers. In this paper, a new method based on AdaBoost is proposed to form a good sub-set of features. This method evaluates the performance of each feature, and then selects features from the extracted features for classification...
