获取图片所有对应坐标中的像素值。直接上代码了

#include <iostream>#include "cv.h"#include <highgui.h>#include<fstream>using namespace std;int main(){    IplImage *img = cvLoadImage("C:\\Users\\Sunstarisme\\Desktop\\Lemon\\All Frames\\2.bmp", CV_LOAD_IMAGE_COLOR);    uchar *data = (uchar *)img->imageData;    int step = img->widthStep / sizeof(uchar);    int channels = img->nChannels;    int R, G, B;    ofstream fout;    fout.open("RGB.txt", ios::app);    for(int i = 0; i < img->height; i++)    {        for(int j = 0; j < img->width; j++)        {            B = (int)data[i * step + j * channels + 0];            G = (int)data[i * step + j * channels + 1];            R = (int)data[i * step + j * channels + 2];            fout << "( " << i << ", " << j << " ) = ( " << R << "," << G << "," << B << ")" << endl;        }    }    fout.close();    return 0;}

结果是：
