Performs PCA analysis of the vector set. First, it uses cvCalcCovarMatrix to compute covariation matrix and then it finds its eigenvalues and eigenvectors. The output number of eigenvalues/eigenvectors should be less than or equal to MIN(rows(data),cols(data)).

Parameters

data
Type: System..::..IntPtr
The input data; each vector is either a single row (CV_PCA_DATA_AS_ROW) or a single column (CV_PCA_DATA_AS_COL).
avg
Type: System..::..IntPtr
The mean (average) vector, computed inside the function or provided by user
eigenvalues
Type: System..::..IntPtr
The output eigenvalues of covariation matrix.
eigenvectors
Type: System..::..IntPtr
The output eigenvectors of covariation matrix (i.e. principal components); one vector per row.
flags
Type: Emgu.CV.CvEnum..::..PCA_TYPE
