To perform localization, one can take a sliding window approach, but this strongly increases the computational cost, because the classifier function has to be evaluated over a large set of candidate subwindows. In this paper, we propose a simple yet powerful branchand- bound scheme that allows efficient maximization of a large class of classifier functions over all possible subimages. It converges to a globally optimal solution typically in sublinear time. We show how our method is applicable to different object detection and retrieval scenarios. The achieved speedup allows the use of classifiers for localization that formerly were considered too slow for this task, such as SVMs with a spatial pyramid kernel or nearest neighbor classifiers based on the 2-distance. We demonstrate state-of-the-art performance of the resulting systems on the UIUC Cars dataset, the PASCAL VOC 2006 dataset and in the PASCAL VOC 2007 competition.","lang":"eng"}],"quality_controlled":0,"type":"conference","status":"public","date_created":"2018-12-11T12:04:46Z","author":[{"orcid":"0000-0001-8622-7887","full_name":"Christoph Lampert","first_name":"Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","last_name":"Lampert"},{"last_name":"Blaschko","full_name":"Blaschko,Matthew B","first_name":"Matthew"},{"last_name":"Hofmann","first_name":"Thomas","full_name":"Hofmann,Thomas"}],"doi":"10.1109/CVPR.2008.4587586","date_updated":"2021-01-12T07:51:40Z","conference":{"name":"CVPR: Computer Vision and Pattern Recognition"},"day":"18","publist_id":"2644","publication_status":"published","citation":{"ama":"Lampert C, Blaschko M, Hofmann T.
