OpenLvVision_OpenCv.lvlib:Mahalanobis.vim

Calculates the Mahalanobis distance between two vectors.

The function Mahalanobis calculates and returns the weighted distance between two vectors:

$ d(\texttt{vec1}, \texttt{vec2}) = \sqrt{\sum_{i,j} \texttt{icovar}(i,j) \cdot (\texttt{vec1}(i) - \texttt{vec2}(i)) \cdot (\texttt{vec1}(j) - \texttt{vec2}(j))} $

The covariance matrix may be calculated using the calcCovarMatrix function and then inverted using the invert function (preferably using the DECOMP_SVD method, as the most accurate).

For detailed information, please refer to the OpenCV documentation
