Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipQueryKeyPoints

ITcVnContainer*

Container with query Keypoints (i.e. keypoints of a reference/template image) of type CTcVnContainer_Vector_TcVnKeyPoint

ipTrainKeyPoints

ITcVnContainer*

Container with training Keypoints (i.e. keypoints of a source/input image) of type CTcVnContainer_Vector_TcVnKeyPoint

ipMatches

ITcVnContainer*

Container with matches between query and train Keypoints (CTcVnContainer_Vector_TcVnDMatch).

ipQueryCoordinates

ITcVnContainer*&

Returns a container with the coordinates of keypoints from the query Keypoints that exist in ipMatches (CTcVnContainer_Vector_TcVnPoint2_REAL)

ipTrainCoordinates

ITcVnContainer*&

Returns a container with the coordinates of keypoints from the training Keypoints that exist in ipMatches (CTcVnContainer_Vector_TcVnPoint2_REAL)
