通过官网进行OpenCV3.4.1的安装，安装步骤可以参考链接: https://cungudafa.blog.youkuaiyun.com/article/details/84451066.

1.2 Linux下编程

1.2.1 编写一个打开图片进行特效显示的代码

代码如下：

#include <opencv2/highgui.hpp>
#include <opencv2/opencv.hpp>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
   
	CvPoint center;
    double scale = -3; 

	IplImage* image = cvLoadImage("lena.jpg");
	argc == 2? cvLoadImage(argv[1]) : 0;
	
	cvShowImage("Image", image);
	
	
	if (!image) return -1; 	center = cvPoint(image->width / 2, image->height / 2);
	for (int i = 0;i<image->height;i++)
		for (int j =
