Method of calculating the  Covariance Matrix : \n
\c True : The feature vector is transposed into the tangent space. \n  
\c False : The upper triangular matrix is used. \n

 * |OVP_DocBegin_BoxAlgorithm_FeatureVectorToCovarianceMatrix_Setting2|
Link to the Reference Matrix CSV. A square matrix of size NxN with N the number of Features. The reference matrix is the same size as the input covariance matrices. The reference matrix is useful for calculating the feature vector on the tangent space.\nRemarks : If no reference an identity matrix is used.
