i tried to do a code that find all objects using a template .The logCat don't give me any errors but the application stopped this is the code .Please help me
public Mat matchTemplate(String inFile, String templateFile,String outFile, int match_method) {
Log.i(TAG, "Running Template Matching");
Mat img = Imgcodecs.imread(inFile);
Mat templ = Imgcodecs.imread(templateFile);
// / Create the result matrix
int result_cols = img.cols() - templ.cols() + 1;
int result_rows = img.rows() - templ.rows() + 1;
Mat result = new Mat(result_rows, result_cols, CvType.CV_32FC1);
Log.i(TAG,"error debug: "+result.empty());
// / Do the Matching Normalize and Perform the template matching operation
Imgproc.matchTemplate(img, templ, result, match_method);
// Core.normalize(result, result, 0, 1, Core.NORM_MINMAX, -1, new Mat());
Imgproc.threshold(result, result,0.8,1,Imgproc.THRESH_TOZERO);
// / Localizing the best match with minMaxLoc. We localize the minimum and maximum values in the result matrix R by using minMaxLoc.
Point matchLoc;
Point maxLoc;
Point minLoc;
MinMaxLocResult mmr;
boolean iterate = true;
while(true){
// / Localizing the best match with minMaxLoc
mmr = Core.minMaxLoc(result);
matchLoc = mmr.maxLoc;
if(mmr.maxVal >=0.9)
{
// iterate = false;
// / Show me what you got
Imgproc.rectangle(img, matchLoc, new Point(matchLoc.x + templ.cols(),matchLoc.y + templ.rows()), new Scalar(0,0,0));
}
else
break; //No more results within tolerance, break search
}
// Save the visualized detection.
Log.i(TAG, "Writing: " + outFile);
Imgcodecs.imwrite(outFile, img);
return img;
}
