#include <cv.h>
#include <highgui.h>

int main(int argc, char* argv[]) {
  if (argc < 2) {
    printf("Usage: ./opencv_hello <file.png>\n");
    return -1;
  }

  IplImage *img = cvLoadImage(argv[1], CV_LOAD_IMAGE_UNCHANGED);
  if (!img) {
    return -1;
  }

  cvNamedWindow("display", CV_WINDOW_AUTOSIZE);
  cvShowImage("display", img);
  cvWaitKey(0);

  return 0;
}

OpenCV Configuration
