pub fn norm_l2(src: &impl GMatTraitConst) -> Result<GScalar>Expand description
Calculates the absolute L2 norm of a matrix.
This version of normL2 calculates the absolute L2 norm of src.
As example for one array consider the function .
The
norm for the sample value
is calculated as follows
\f{align*}
| r(-1) |{L_2} &= \sqrt{(-1)^{2} + (2)^{2}} = \sqrt{5} \
\f}
and for
the calculation is
\f{align*}
| r(0.5) |{L_2} &= \sqrt{(0.5)^{2} + (0.5)^{2}} = \sqrt{0.5} \
\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.norml2”
