I want to manually set every pixel's R,G, and B floating point values to 0.4. When I run the following code I get an error. What am I doing wrong?
The error at run-time is:
> *** Error in `./program': free(): invalid next size (fast):> 0x00000000019f9080 *** Aborted
#include "opencv2/highgui/highgui.hpp"
#include
using namespace std;
using namespace cv;
int main()
{
Mat imageF(36,36, CV_32F);
int i = 0;
int j = 0;
float blue = 0.0;
float green= 0.0;
float red= 0.0;
Vec3f intensity;
for(j=0; j(j, i);
//blue = intensity.val[0];
//green = intensity.val[1];
//red = intensity.val[2];
blue = red = green = 0.4;
intensity.val[0] = blue;
intensity.val[1] = green;
intensity.val[2] = red;
imageF.at(j, i) = intensity;
}
}
imshow("Output", imageF);
waitKey(0);
return 0;
}
