I want to count the pedestrian amount from image.so it's working. now i have to do within button click. if i click button, this function want to run and count the pedestrian. my codes here. how can i do that. help me.

include "stdafx.h"

include <stdio.h>

include <cv.h>

include <iostream>

include <highgui.h>

using namespace cv; using namespace std; void detect(IplImage *faces); int main() { freopen("out.txt","w",stdout); CascadeClassifier cascade;

if (!cascade.load("haarcascade_frontalface_alt.xml")) return -1;

Mat src = imread("people1.jpg"); if (src.empty()) return -1;

Mat gray; cvtColor(src, gray, CV_BGR2GRAY); equalizeHist(gray, gray);

vector<rect> faces; cascade.detectMultiScale(gray, faces, 1.2, 3);

for (int i = 0; i < faces.size(); i++) { Rect r = faces[i]; rectangle(src, Point(r.x, r.y), Point(r.x + 5, r.y + 5), CV_RGB(0,255,0)); } std::cout << "Total: " << faces.size() << " faces" << std::endl; imshow("src", src); waitKey(0);

return 0;

}
