I'm using OpenCV (in Java) to implement curved line detection,
to detection a curve like the yellow one in this image.
I do not know how. Help.

detection curve line
MatOfInt4 lines = new MatOfInt4(); Imgproc.HoughLinesP(mat, lines, 1, Math.PI / 180, 20, 15, 10); for (int i = 0; i < lines.cols(); i++) { double[] l = lines.get(0, i); Point startPoint = new Point(l[0], l[1]); Point endPoint = new Point(l[2], l[3]); Core.line(mat, startPoint, endPoint, new Scalar(255, 0, 255), 1); }
