[IEEE 2018 24th International Conference on Pattern Recognition (ICPR) - Beijing, China (2018.8.20-2018.8.24)] 2018 24th International Conference on Pattern Recognition (ICPR) - Cross Modal Multiscale Fusion Net for Real-time RGB-D Detection

摘要： This paper presents a novel multi-modal CNN architecture for object detection by exploiting complementary input cues in addition to sole color information. Our one-stage architecture fuses the multiscale mid-level features from two individual feature extractor, so that our end-to-end net can accept crossmodal streams to obtain high-precision detection results. In comparison to other crossmodal fusion neural networks, our solution successfully reduces runtime to meet the real-time requirement with still high-level accuracy. Experimental evaluation on challenging NYUD2 dataset shows that our network achieves 49.1% mAP, and processes images in real-time at 35.3 frames per second on one single Nvidia GTX 1080 GPU. Compared to baseline one stage network SSD on RGB images which gets 39.2% mAP, our method has great accuracy improvement.
