关于YOLO：

YOLO——You Only Look Once

Faster RCNN需要对20k个anchor box进行判断是否是物体，然后再进行物体识别，分成了两步。

YOLO(You Only Look Once)则把物体框的选择与识别进行了结合，一步输出，即变成”You Only Look Once”。

所以识别速度非常快，达到每秒45帧，而在快速版YOLO(Fast YOLO，卷积层更少)中，可以达到每秒155帧。

关于DarkNet：

\#Darknet\#

Darknet is an open source neural network framework written in C and CUDA. It is fast, easy to install, and supports CPU and GPU computation.

For more information see the \[Darknet project website\](http://pjreddie.com/darknet or https://github.com/pjreddie/darknet).

安装指南：http://pjreddie.com/darknet/install/

这个是我见过安装最简单的开源库了！！！

linux下，解压后直接make就可以了，如果你想实时可视化，开启OPENCV=1，关于这里配置OPENCV时需要注意下：

ifeq ($(OPENCV), 1)

COMMON+= -DOPENCV-I/usr/local/include

CFLAGS+= -DOPENCV

LDFLAGS+= -L/usr/local/lib -lopencv\_core -lopencv\_highgui -lopencv\_imgproc

endif

编译好后，下载训练好的权值数据yolo.weights(我下的是700M左右的)，同时使用了相应的yolo.cfg，从官网下的没运行成功！！！

可见CPU下Debug耗时太长啊！
