Function opencv::gapi::norm_l1

source · 
pub fn norm_l1(src: &GMat) -> Result<GScalar>
Expand description

Calculates the absolute L1 norm of a matrix.

This version of normL1 calculates the absolute L1 norm of src.

As example for one array consider the function inline formula. The inline formula norm for the sample value inline formula is calculated as follows \f{align*} | r(-1) |{L_1} &= |-1| + |2| = 3 \ \f} and for inline formula the calculation is \f{align*} | r(0.5) |{L_1} &= |0.5| + |0.5| = 1 \ \f}

Supported matrix data types are [CV_8UC1], [CV_8UC3], [CV_16UC1], [CV_16SC1], [CV_32FC1].

Note: Function textual ID is “org.opencv.core.matrixop.norml1”

Parameters

  • src: input matrix.
