Logical operations in OpenCV from Java

In OpenCV's C++ API, one can do elementwise boolean operations (and, or, xor, not) using a syntax like this:

Mat a, b;
Mat c = a & b;

and similarly with the others. I know there is no operator overloading in Java; I'm looking for how the Java API exposes the same functionality that was exposed in C++ in that form. I've found the Core.bitwise_* functions already, but those are per bit, not per matrix element.

Mat a, b; // Set these to what you need.
Mat result = new Mat();
Core.bitwise_and(a, b, result);

You can do the same with Core.bitwise_or(...)

This is operator overloading. In java operator overloading is not supported. But if you require something like this you can introduce a method to do this.

For example - 

Mat a, b;
Mat c;
c = Mat.doOperation(a, b);

Where doOperation() is a static method in Mat - 

public static doOperation(Mat a, Mat b){
   //do whatever you want
}
