Human detection using multimodal and multidimensional features
— This paper presents a novel human detection method based on a Bayesian fusion approach using laser range data and camera images. Laser range data analysis groups data points with a novel graph cutting method. Therefore, it computes a belief to each cluster based on the evaluation of multidimensional features that describe geometrical properties. A person detection algorithm based on dense overlapping grid of Histograms of Oriented Gradients (HOG) is processed on the image area determined by each laser cluster. The selection of HOG features and laser features is obtained through a learning process based on a cascade of linear Support Vector Machines (SVM). A technique to obtain conditional probabilities from a cascade of SVMs is here proposed in order to combine the two information together. The resulting human detection consists in a rich information that takes into account the distance of the cluster and the confidence level of both detection methods. We demonstrate the performan...
