基于区域的卷积神经网络(Region-based convolutional neural networks, or regions with CNN feature, R-CNNs)是将深度模型应用于目标检测的一种前沿方法[Girshick et al., 2014]。在本节中,我们将讨论R-CNN和对它们的一系列改进:Fast R-CNN [Girshick, 2015], Faster R-CNN [Ren et al., 2015],和Mask R...
Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks Faster R-CNN = RPN + Fast R-CNN Abstract SPPnet和Fast R-CNN虽然减少了算法运行时间,但region proposal仍然是限制算法速度的瓶颈。而Faster R-CNN提出了Region Proposal Network (RPN),该网络基于卷积特征预测每个位置是否为...

We adapted the join-training scheme of Faster RCNN framework from Caffe to TensorFlow as a baseline implementation for object detection. Our code is made publicly available. This report documents the simplifications made to the original pipeline, with justifications from ablation analysis on both PASCA...
In this paper, we investigate the use of RCNN, which is a deep machine learning technique, for detecting such ROIs only using a small number of labelled WSIs for training. For experimentation, we used real WSIs from a public hospital pathology service in Western Australia. We used 60 WSIs ...
本文是三星北京研发中心提出的R2CNN(Rotational Region CNN),基于Faster R-CNN架构,主要用于文字检测。 Motivation 场景文字检测的难点在于:文字大小不同,高宽比率不同,字体,灯光,透视变形,方向等。对于场景文字识别比普通文字识别差别是预测带方向的轴对称的边界框信息。 本文是三星北京研发中心提出的R2CNN(Rotational...
Conv layers。作为一种CNN网络目标检测方法,Faster RCNN首先使用一组基础的conv+relu+pooling层提取image的feature maps。该feature maps被共享用于后续RPN层和全连接层。 Region Proposal Networks。RPN网络用于生成region proposals。该层通过softmax判断anchors属于positive或者negative,再利用bounding box regression修正anchor...
