how to Reduce false detection of template matching ??
public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
try {
image = inputFrame.rgba();
templ = Utils.loadResource(MainActivity.this, TEMPLATE, Highgui.CV_LOAD_IMAGE_COLOR);
} catch (Exception e) {
Log.d("eeeeeeeee", e.getMessage());
}
Mat template = new Mat(templ.size(), CvType.CV_32F);
Imgproc.cvtColor(templ, template, Imgproc.COLOR_BGR2RGBA);
int match_method = Imgproc.TM_CCOEFF;
// Create the result matrix
int result_cols = image.cols() - template.cols() + 1;
int result_rows = image.rows() - template.rows() + 1;
Mat result = new Mat(result_rows, result_cols, CvType.CV_32F);
// Do the Matching and Normalize
Imgproc.matchTemplate(image, template, result, match_method);
Core.normalize(result, result, 0, 255, Core.NORM_MINMAX, -1, new Mat());
// Localizing the best match with minMaxLoc
Core.MinMaxLocResult mmr = Core.minMaxLoc(result);
Point matchLoc;
if (match_method == Imgproc.TM_SQDIFF || match_method == Imgproc.TM_SQDIFF_NORMED) {
matchLoc = mmr.minLoc;
} else {
matchLoc = mmr.maxLoc;
}
Point pt2 = new Point(matchLoc.x + template.cols(), matchLoc.y + template.rows());
Scalar color = new Scalar(0, 255, 255, 0);
Core.rectangle(image, matchLoc, pt2, color);
return image;
}
