In this paper we propose an improvement to the Implicit Shape Model (ISM) based robust object detection system proposed by Leibe et al. Object detection with ISM allows to approach the classification and tracking in a probabilistic way with multiple hypotheses.

This is done while maintaining the robustness of the original approach. Leibe et al. mentioned a potential solution to overcome the scale problem in the training set, i.e., the usage of the scale produced by the local descriptor. Our proposal is different: since we believe that the scale measure generated by local descriptors is subject to noise, we try to walk around this noise by estimating the scale measure from the only evidence collected in the image.

Abstract

In this paper we propose an improvement to the Implicit Shape Model (ISM) based robust object detection system proposed by Leibe et al. Object detection with ISM allows to approach the classification and tracking in a probabilistic way with multiple hypotheses. Unlike the original approach, our method is independent from object scale in the training sets, and this allows to work with a much smaller training sets and also to avoid to supply information about scale to the trainer. This is done while maintaining the robustness of the original approach. Leibe et al. mentioned a potential solution to overcome the scale problem in the training set, i.e., the usage of the scale produced by the local descriptor. Our proposal is different: since we believe that the scale measure generated by local descriptors is subject to noise, we try to walk around this noise by estimating the scale measure from the only evidence collected in the image.
