Function abs

pub fn abs(m: &impl MatTraitConst) -> Result<MatExpr>

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

• m: matrix.
