Hi i use this code link text but it gives me minVal=maxVal=0.0 !
public void TemplateMatching(Mat mFind,Bitmap dst)
{
Mat Input = new Mat(mFind.width(), mFind.height(), CvType.CV_8UC4);
Utils.bitmapToMat(dst, Input);
Mat mResult8u = new Mat(mFind.width(), mFind.height(), CvType.CV_8UC4);
Mat mResult9u = new Mat(mFind.width(), mFind.height(), CvType.CV_8UC4);
Mat mResult = new Mat(mFind.width(), mFind.height(), CvType.CV_8UC4);
Imgproc.matchTemplate(mFind, Input, mResult, Imgproc.TM_CCOEFF_NORMED);
Core.normalize(mResult, mResult9u, 0, 255, Core.NORM_MINMAX, CvType.CV_8U);
MinMaxLocResult locRes = Core.minMaxLoc(mResult9u);
double minVal = locRes.minVal;
Point minLoc = locRes.minLoc;
double maxVal = locRes.maxVal;
Point maxLoc = locRes.maxLoc;
maxLoc.x+=25;
maxLoc.y+=25;
Point point = new Point();
point.x=maxLoc.x+Input.cols();
point.y=maxLoc.y+Input.rows();
double thresholds=0.08;
Log.w("max val", maxVal+"");
Log.w("min val", minVal+"");
if(maxVal>=thresholds)
Core.rectangle(mFind, maxLoc,point, new Scalar(0, 255, 0, 255), 3);
Bitmap bmp3= Bitmap.createBitmap(mFind.cols(), mFind.rows(),Bitmap.Config.ARGB_8888);
Utils.matToBitmap(mFind, bmp3);
imgb.setImageBitmap(bmp3);
}
