因为没有GPU,所以在CPU下训练自己的数据,中间遇到了各种各样的坑,还好没有放弃,特以此文记录此过程. 1.在CPU下配置faster r-cnn,参考博客:http://blog.csdn.net/wjx2012yt/article/details/52197698#quote 2.在CPU下训练数据集,需要对py-faster-rcnn内的roi_pooling_layer和smooth_L1_loss_layer改为CPU版本, 并重新编译.这位博主对其进行了修改,可直接进行替换:htt…

把r-cnn系列总结下,让整个流程更清晰. 整个系列是从r-cnn至spp-net到fast r-cnn再到faster r-cnn.  RCNN 输入图像,使用selective search来构造proposals(大小不一,需归一化),输入到CNN网络来提取特征, 并根据特征来判断是什么物体(分类器,将背景也当做一类物体),最后是对物体的区域(画的框)进行微调(回归器). 由下面的图可看出,RCNN分为四部分,ss(proposals),CNN,分类器,回归器,这四部分是相对独立的.改进的…
