Deformable Part Models Revisited: A Performance Evaluation for Object Category Pose Estimation

Deformable Part Models (DPMs) as introduced by Felzenszwalb et al. have shown remarkably good results for category-level object detection. In this paper, we explore whether they are also well suited for the related problem of category-level object pose estimation. To this end, we extend the original DPM so as to improve its accuracy in object category pose estimation and design novel and more effective learning strategies. We benchmark the methods using various publicly available data sets. Provided that the training data is sufficiently balanced and clean, our method outperforms the state-of-the-art.
