As you can see from your stacktrace, openCV cannot find an implementation of Rect if you use this prototype :
Imgproc.rectangle_1(long, double, double, double, double, double, double, double, double, int)
Looking at the official documentation here, openCV expects something like this:
Imgproc.rectangle(Mat src,Point pt1, Point pt2, Scalar color, int thickness, int lineType, int)
and so its prototype is Imgproc.rectangle(Mat,Point, Point, Scalar, int, int, int)
that is different from yours.
Alternatively, passing a Rect instead of Points:
Imgproc.rectangle(Mat src,Rectangle rect, Scalar color, int thickness, int lineType, int)
and so its prototype is Imgproc.rectangle(Mat,Rect, Scalar, int, int, int)
.
I think that yu have to double check your code to match these prototypes.
