We argue for a data-driven, semantic approach for ranking object proposals. Our framework, which we call DeepBox, uses convolutional neural networks (CNNs) to rerank proposals from a bottom-up method. We use a novel four-layer CNN architecture that is as good as much larger networks on the task of evaluating objectness while being much faster. We show that DeepBox significantly improves over the bottom-up ranking, achieving the same recall with 500 proposals as achieved by bottom-up methods with 2000. This improvement generalizes to categories the CNN has never seen before. Finally, DeepBox has a significant impact on the performance of the object detector, reducing by 40% the total time taken for detection.", "revisions": [ { "version": "v1", "updated": "2015-05-08T19:24:17.000Z" } ], "analyses": { "keywords": [ "convolutional networks", "learning objectness", "novel four-layer cnn architecture", "bottom-up method", "convolutional neural networks" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150502146K" } } }
