Girshick, Ross. “Fast r-cnn.” Proceedings of the IEEE International Conference on Computer Vision. 2015. 继2014年的RCNN之后,Ross Girshick在15年推出Fast RCNN,构思精巧,流程更为紧凑,大幅提升了目标检测的速度.在Github上提供了源码. 之所以提出Fast R-CNN,主要是因为R-CNN存在以下几个问题: 训练分多步.通过上一篇博文我们知道R-CNN的训练先…
Ren, Shaoqing, et al. “Faster R-CNN: Towards real-time object detection with region proposal networks.” Advances in Neural Information Processing Systems. 2015. 本文是继RCNN[1],fast RCNN[2]之后,目标检测界的领军人物Ross Girshick团队在2015年的又一力作.简单网络目标检测速度达到17fps,在PASCAL…
This results in a significant improvement in speed for high-accuracy detection(59 FPS with mAP 74.3% on VOC2007 test, vs Faster-rcnn 7 FPS with mAP 73.2% or YOLO 45 FPS with mAP 63.4%) 图1 SSD和其它算法的性能比较 一.SSD网络总体架构 图2 SSD网络架构(精简版) 图3 SSD网络架构(细节版) SSD算…
