Detailed Description

Matrix expression representation.

This is a list of implemented matrix operations that can be combined in arbitrary complex expressions (here A, B stand for matrices ( Mat ), s for a scalar ( Scalar ), alpha for a real-valued scalar ( double )):

Friends And Related Function Documentation

§ abs() [1/2]

MatExpr abs ( const Mat m)
related

Calculates an absolute value of each matrix element.

abs is a meta-function that is expanded to one of absdiff or 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 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 .

Parameters
mmatrix.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
