Hello,

I am using bif function (bif.cpp) from the extra module 'face' of Opencv-3.0.1. When I run the function for a test image, the returned feature vector includes many NaN values. Could you please help me understand why this is happening?

#include "cv.hpp"
#include "opencv.hpp"
#include "highgui.h"
#include "bif.hpp"
#include <iostream>

using namespace cv;
using namespace std;

int main(int argc, char** argv) {

    cv::Mat fea;
    cv::Ptr<cv::face::BIF> bif = cv::face::createBIF();
    cv::Mat image(60, 60, CV_32F);
    cv::theRNG().fill(image, cv::RNG::UNIFORM, -1, 1);
    bif->compute(image, fea);
    cout << "fea = " << endl << " " << fea << endl << endl;

    waitKey(0);

    return 0;
}

Thank you in advance.

Thank you in advance.

EDIT: Sorry for my delayed edit, but please let me ask something more. I have done the changes you suggested and for most of the images the NaN value disappeared. However, there still the problem is not fixed for some other images where the problem insists, images, I am giving an example bellow. below. Could you please give some help on this?

 sd = sqrt((sd / area - mean  mean) < 0 & abs((sd / area - mean  mean)) < std::numeric_limits<double>::epsilon() ? 0 : (sd / area - mean * mean));
