``abs`` is a meta-function that is expanded to one of :ocv:func:`absdiff` or :ocv:func:`convertScaleAbs` forms:
* ``C = abs(A-B)`` is equivalent to ``absdiff(A, B, C)``
* ``C = abs(A)`` is equivalent to ``absdiff(A, Scalar::all(0), C)``
* ``C = Mat_<Vec<uchar,n> >(abs(A*alpha + beta))`` is equivalent to :ocv:funcx:`convertScaleAbs` (A, C, alpha, beta)
* ``C = Mat_<Vec<uchar,n> >(abs(A*alpha + beta))`` is equivalent to ``convertScaleAbs(A, C, alpha, beta)``
The output matrix has the same size and the same type as the input one except for the last case, where ``C`` is ``depth=CV_8U`` .
