چکیده

The present paper addresses pedestrian detection using local boosted features that are learned from a small set of training images. Our contribution is to use two boosting steps. The first one learns discriminant local features corresponding to pedestrian parts and the second one selects and combines these boosted features into a robust class classifier. In contrast of other works, our features are based on local differences over Histograms of Oriented Gradients (HoGs). Experiments carried out to a public dataset of pedestrian images show good performance with high classification rates.

Local Decorrelation For Improved Pedestrian Detection

Even with the advent of more sophisticated, data-hungry methods, boosted decision trees remain extraordinarily successful for fast rigid object detection, achieving top accuracy on numerous datasets. While effective, most boosted detectors use decision trees with orthogonal (single feature) splits, and the topology of the resulting decision boundary may not be well matched to the natural topolo...

Empirical Study of Boosted Weak Classifier in Object Detection Problem

In this paper, we study the use of boosted weak classifiers selected with AdaBoost algorithm in object detection. Our work is motivated by the good performance of AdaBoost in selecting discriminative features and the effectiveness of Classification and Regression Tree (CART) compared with other classification methods. First, we study the cascaded structure of the boosted weak classifier detecto...

Real-time Pedestrian Detection Using a Boosted Multi-layer Classifier∗

Techniques for detecting pedestrian in still images have attracted considerable research interests due to its wide applications such as video surveillance and intelligent transportation systems. In this paper, we propose a novel simpler pedestrian detector using state-of-the-art locally extracted features, namely, covariance features. Covariance features were originally proposed in [1,2]. Unlik...

Pedestrian Detection in Infrared Outdoor Images Based on Atmospheric Situation Estimation

Observation in absolute darkness and daytime under every atmospheric situation is one of the advantages of thermal imaging systems. In spite of increasing trend of using these systems, there are still lots of difficulties in analysing thermal images due to the variable features of pedestrians and atmospheric situations. In this paper an efficient method is proposed for detecting pedestrians in ...
