这一切始于 2014 年的一篇论文「Rich feature hierarchies for accurate object detection and semantic segmentation」(R-CNN),其使用了称为 Selective Search 的算法用来提取感兴趣候选区域,并用一个标准的卷积神经网络(CNN) 去分类和调整这些区域。Fast R-CNN 从 R-CNN 演变优化而来,Fast R-CNN 发布于 2015 年...
而anchors的生成过程具体是这样:sliding window的中心在image上对应一片区域(相当于中心位置的神经元在image上的感受野,当n=3时,ZF 模型中中心位置的神经元在image上的感受野大小为171*171;VGG 模型中为228*228),计算出该区域的中心位置后以该位置为中心,按3种scale(即面积,128*128,256*256,512*512)、每种sca...

2.仿照model文件夹下文件,准备好相应model和配置文件 3.仿照settings_local.py编写settings_local.template-<your_network>.py 五.总结 通过非参数的可视化方法,我们从一定角度上探索了CNN这个“黑盒”,我们知道了CNN是从底层到高层,从抽象到具体来学习特征的,同时这个可视化也为我们改进网络结构提供了可能!

spatial hierarchies of features, enabling them to detect patterns, shapes, textures, and objects from raw pixel values. This ability to learn hierarchical feature representations makes CNNs the go-to model for computer vision tasks like image classification, object detection, and segmentation. ...
