	argc--;
	argv++;
	
	if(argc < 1) {
		cout << "Usage: houghTransform <input image> [resolution (optional)]" << endl;

	}
	
	// Load image
	Image src;
	int result = src.LoadPPM(argv[0]);
	
	if(result != 0) {

		return 1;
	}

	int resolution = 1;
	if(argc > 1) {
		resolution = atoi(argv[1]);
	}
	
	// convert image if needed
	Image greySrc = src;

		ColorConversion::ToGrey(src, greySrc);
	} 

	// times
