IoU 计算

基于候选区域的目标检测算法

IoU 计算假设：预测框坐标为$(x_1,y_1,w_1,h_1)$，真实目标框坐标为$(x_2,y_2,w_2,h_1)$ 计算过程：判断预测框与真实框时候重合计算重合的面积以及IoU Python程序实现： def IOU(Prediction, GroundTruth): x1 = Prediction[0] y1 =...

Identity Mappings in Deep Residual Networks

论文阅读笔记

论文笔记论文题目：Identity Mappings in Deep Residual Networks 1、Introduction 一般残差单元过程可以公式化为。和$x_{l+1}$ 为第$l$ 层的输入和输出。在ResNet V1中为恒等映射，$f$ 为ReLU函数。采用恒等映射的收敛速度最快，训练的错误率下降最快使用“纯净”的信息路径有助于更易于优化...
