OpenCVSharpにてテンプレートマッチングを行う

OpenCVSharpにて、テンプレートマッチングを行う方法です。Mat形式に対応しています。

	try {
	Mat result = new Mat(mat.Height - matTemplate.Height + 1, mat.Width - matTemplate.Width + 1, MatType.CV_8UC1);
	Cv2.MatchTemplate(mat, matTemplate, result, MatchTemplateMethod.CCoeff);
	OpenCvSharp.CPlusPlus.Point minPoint = new OpenCvSharp.CPlusPlus.Point();
	OpenCvSharp.CPlusPlus.Point maxPoint = new OpenCvSharp.CPlusPlus.Point();
	Cv2.MinMaxLoc(result, out minPoint, out maxPoint);
	Mat img = mat.Clone();
	Cv2.Rectangle(img, rect, new OpenCvSharp.CPlusPlus.Scalar(0, 0, 255), 2);
	Cv2.Resize(img, img, new OpenCvSharp.CPlusPlus.Size(), 0.3, 0.3, Interpolation.Lanczos4);
	Cv2.ImShow("result", img);
	} catch (OpenCvSharp.OpenCVException ee) {
	System.Diagnostics.Debug.WriteLine(ee.ErrMsg);
	}
