I am trying to reproduce the code displayed [here](http://docs.opencv.org/2.4/doc/tutorials/features2d/feature_homography/feature_homography.html) (it was an absolute pain to debug).
The actual code is:
int main(int argc, char* argv[]) {
initModule_nonfree();
Mat img_object = imread("/home/razakhel/Downloads/base.png" CV_IMREAD_GRAYSCALE);
Mat img_scene = imread("/home/razakhel/Downloads/pattern.png" CV_IMREAD_GRAYSCALE);
if (!img_object.data || !img_scene.data) {
std::cout<< " --(!) Error reading images " << std::endl; return -1;
}
//-- Step 1: Detect the keypoints using SURF Detector
int minHessian = 400;
SurfFeatureDetector detector(minHessian);
std::vector keypoints_object, keypoints_scene;
detector.detect(img_object, keypoints_object); // <= Core dumped
detector.detect(img_scene, keypoints_scene);
[...]
return 0;
}
The error appears on the line commented as such. The `base.png` is a 1366x768 picture (I tried with it rescaled to 640x380, same thing). The `pattern.png` is scaled at 205x180, but the code isn't reaching its import anyway. I assume it is unrelated to the size, but we never know.
I've been searching for answers for a while, but all I've been able to find was a problem related to the missing `initModule_nonfree()`.
If anyone has an idea, I'd gladly try it.
