void cv::sfm::meanAndVarianceAlongRows | ( | InputArray | A, |
OutputArray | mean, | ||
OutputArray | variance | ||
) |
#include <opencv2/sfm/numeric.hpp>
Computes the mean and variance of a given matrix along its rows.
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 reduce but with Variance function.
Mat cv::sfm::skew | ( | InputArray | x | ) |
#include <opencv2/sfm/numeric.hpp>
Returns the 3x3 skew symmetric matrix of a vector.
x | Input 3x1 vector. |
