## Xcode上opencv显示图片 ##

int main( )
    {
        //读入图像
        //原图像
        Mat srcImage=imread("/Users/liyixin/Pictures/tree.jpg");
    
        //创建窗口
        namedWindow("FomalSize",CV_WINDOW_NORMAL);
    
        //显示原图
        imshow("FomalSize",srcImage);
        waitKey(0);
    }

## Xcode上opencv缩小图像 ##

#include <iostream>
    #include <opencv2/opencv.hpp>
    #include <opencv2/highgui/highgui.hpp>
    #include <opencv/cvaux.hpp>
    #include <fstream>
    using namespace std;
    using namespace cv;
    int main( )
    {
     //读入图像
        //原图像
        Mat srcImage=imread("/Users/..../Pictures/tree.jpg");
        //修改尺寸后的图像
        Mat samImage; samImage=srcImage;
    
        //创建窗口
        //namedWindow("FomalSize",CV_WINDOW_NORMAL);
        //namedWindow("Smallsize",CV_WINDOW_NORMAL);
    
        //显示原图
        //imshow("FomalSize",srcImage);
    
        //尺寸调整
        resize(srcImage,samImage,Size(srcImage.cols/8,srcImage.rows/8),0,0,INTER_LINEAR);
    
        //显示尺寸调整后的图
        imshow("Smallsize", samImage);
        waitKey(0);
    }

推荐两个博客:(写得很好,可以借鉴~)
