This paper presents how we can achieve the state-of-the-art accuracy in multicategory object detection task while minimizing the computational cost by adapting and combining recent technical innovations. Following the common pipeline of “CNN feature extraction + region proposal + RoI classification”, we mainly redesign the feature extraction part, since region proposal part is not computationally expensive and classification part can be efficiently compressed with common techniques like… CONTINUE READING

Key Quantitative Results

  • We obtained solid results on well-known object detection benchmarks: 81.8% mAP (mean average precision) on VOC2007 and 82.5% mAP on VOC2012 (2nd place), while taking only 750ms/image on Intel i7-6700K CPU with a single core and 46ms/image on NVIDIA Titan X GPU.
