Values

Name	Description
TCVN_OM_PCA	Apply the PCA on the points and calculate the mean point as the center point and the rotation angle of the main principal axis
TCVN_OM_FITELLIPSE	Fit an ellipse around the points and calculate the center point and the rotation angle of the main axis
TCVN_OM_MOMENTS	Calculate the moments of the points and estimate the center and the rotation angle
TCVN_OM_ENCLOSINGRECT	Calculate a minimum area rectangle enclosing the points and calculate the center point and the rotation angle of the rectangle
