How to perform a union operation in java opencv

Question

I need to write an equivalent Java OpenCV code as this C++ code

Mat1b mask1, mask2;
inRange(hsv, Scalar(0, 70, 50), Scalar(10, 255, 255         


        

Answer 1

I think what you're mistaking is that you are trying to compare two Mat object refrences and not the values beneath them. I'm not super familiar with openCV but my guess is you are trying to combine the values under them, so you could use the method https://docs.opencv.org/java/2.4.2/org/opencv/core/Mat.html#nativeObj. which that line in question would be re-written as: Mat hsvThres = new Mat(mask1.nativeObj | mask2.nativeObj);
