Unformatted text preview: Evaluating multi-class learning strategies in a hierarchical framework for object detection. Sanja Fidler, Marko Boben, Aleš Leonardis. http://vicos.fri.uni-lj.si/ Summary Objects are represented with a hierarchical compositional shape vocabulary which is learned from images. We evaluate 3 different strategies for learning a hierarchical multi-class object vocabulary for object detection: independent, joint and sequential training. We explore and compare their computational behavior (space and time) and detection performance as a function of the number of learned object classes on several recognition datasets. Results 10 classes. 50 classes. Detections Sharing between visually similar and dissimilar classes. 2 classes. Ind. Joint Seq. Joint ...
