int extract_selected_keypoints_positions
(
	Matrix **pos_mpp,
	const Keypoint_vector *kvp,
	const Int_vector *mask_ivp
);

DESCRIPTION

Input parameters: Matrix** pos_mpp - where to store the position of the keypoints Keypoint_vector *kvp - contains image keypoints and descriptors Int_vector *mask_ivp - if an element is negative, then the corresponding element in the Keypoint_vector is not extracted.

RETURNS

an error code.
