PCACompute(InputArray, InputOutputArray, OutputArray, int)

PCA of the supplied dataset.

public static void PCACompute(InputArray data, InputOutputArray mean, OutputArray eigenvectors, int maxComponents = 0)

Parameters

data InputArray

input samples stored as the matrix rows or as the matrix columns.

mean InputOutputArray

optional mean value; if the matrix is empty (noArray()), the mean is computed from the data.

eigenvectors OutputArray

eigenvectors of the covariation matrix

maxComponents int

Number of components that PCA should retain; by default, all the components are retained.
