Function opencv::sfm::mean_and_variance_along_rows

pub fn mean_and_variance_along_rows(
    a: &dyn ToInputArray, 
    mean: &mut dyn ToOutputArray, 
    variance: &mut dyn ToOutputArray
) -> Result<()>

Computes the mean and variance of a given matrix along its rows.

Parameters

• A: Input NxN matrix.
• mean: Output Nx1 matrix with computed mean.
• variance: Output Nx1 matrix with computed variance.

It computes in the same way as woud do @ref reduce but with \a Variance function.
