To save someone googling, the referenced "Is object detection for free" paper is at http://leon.bottou.org/publications/pdf/cvpr-2015.pdf http://leon.bottou.org/publications/pdf/cvpr-2015.pdf I also just came across "Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks", which looks interesting and is at https://arxiv.org/pdf/1506.01497.pdf https://arxiv.org/pdf/1506.01497.pdf (I'll be reading these after work tonight.)
