cascade classifier doesnot work for image input
given below is my code
#include "opencv2/objdetect/objdetect.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <iostream>
#include <stdio.h>
using namespace std;
using namespace cv;
int main()
{
Mat new=imread("F:\new.jpg");
namedWindow("HAAR");
CascadeClassifier face_cascade;
vector<Rect> faces;
Mat frame_gray;
cvtColor( new, frame_gray, CV_BGR2GRAY );
equalizeHist( frame_gray, frame_gray );
if( !face_cascade.load( "haarcascade_frontalface_alt.xml") )
{
printf("--(!)Error loading\n");
return -1;
};
face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30, 30) );
for( size_t i = 0; i < faces.size(); i++ )
{
Point center( faces[i].x + faces[i].width*0.5, faces[i].y + faces[i].height*0.5 );
ellipse( frame, center, Size( faces[i].width*0.5, faces[i].height*0.5), 0, 0, 360, Scalar( 255, 0, 255 ), 4, 8, 0 );
}
imshow("HAAR", frame );
}
MS visual studio 2010 and opencv 2.4.9 are used. no error is displayed build is successful
Please format your code (as it's done now) and show us the image you are using. By the way, it is a bad habit to name your image "new" and you haven't checked that your image is loaded. Try to use "F:\\new.jpg" (with two \ instead of one).
now replaced variable name 'new' with 'frame' sorry to post the wrong code
