如何使用CImg从显示的图像中选择区域 [英] How to select an area from displayed image using CImg

问题描述

大家好，

这是我编写的一小段代码，是我在C ++中进行图像处理工作的开始.

#include "../CImg.h"
#include <iostream> 
using namespace std;
using namespace cimg_library;
int main(int argc,char**argv)
{
 CImg<int> img(argv[1]);
 CImgDisplay disp;
 disp.assign(img);
 while(!disp.is_closed)
    disp.wait();
 return 0;  
}

这是我的问题:

我想从显示的图像中选择一个区域.有人可以告诉我如何从显示的图像中选择一个区域并存储选定的像素，然后在不同的显示窗口中显示选定的区域.如果有人可以提供代码，那将对我有很大帮助.

谢谢大家

 16     CImg <int> SelectedImageCords = image.get_select(disp,2,0,0);
 17     CImg <unsigned char> SelectedImage = image.get_crop(SelectedImageCords(0
    ),SelectedImageCords(1),SelectedImageCords(3),SelectedImageCords(4));

 19     CImgDisplay disp2(SelectedImage,"Selected Image");

Hi All,

This is small piece of code written by me as a start up for my image processing work in C++.

#include "../CImg.h"
#include <iostream> 
using namespace std;
using namespace cimg_library;
int main(int argc,char**argv)
{
 CImg<int> img(argv[1]);
 CImgDisplay disp;
 disp.assign(img);
 while(!disp.is_closed)
    disp.wait();
 return 0;  
}

Here is my question:

I want to select an area from the displayed image. Can someone tell me how to select an area from displayed image and store the selected pixels, and display the selected region in different display window. If someone can provide code, it will be of great help to me.

Thank you all
