FUNCTIONnorm1

RETURN TYPEnumber

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Calculates an absolute difference norm or a relative difference norm.

This version of cv::norm calculates the absolute difference norm or the relative difference norm of arrays src1 and src2. The type of norm to calculate is specified using #NormTypes.

norm1(src1: Mat, src2: Mat, normType: number, mask: Mat): number;

3 available overloads

norm1(src1: Mat, src2: Mat): number;

norm1(src1: Mat, src2: Mat, normType: number): number;

norm1(src1: Mat, src2: Mat, normType: number, mask: Mat): number;

src1: first input array.
src2: second input array of the same size and the same type as src1.
normType: type of the norm (see #NormTypes).
mask: optional operation mask; it must have the same size as src1 and type CV_8UC1, CV_8S1 or CV_BoolC1.

Returns

The number result.
