opencv的简单使用

安装opencv 先安装这些包，不然后面会有各种各样的错误发生

$ sudo apt-get install cmake libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
$ sudo apt-get install libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff5-dev libdc1394-22-dev         # 处理图像所需的包
$ sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev liblapacke-dev
$ sudo apt-get install libxvidcore-dev libx264-dev         # 处理视频所需的包
$ sudo apt-get install libatlas-base-dev gfortran          # 优化opencv功能
$ sudo apt-get install ffmpeg

编译选项

  g ++ -o test_1 test_1.cpp`pkg-config opencv --cflags --libs`
