|
ipQueryKeyPoints |
Container with query Keypoints (i.e. keypoints of a reference/template image) of type CTcVnContainer_Vector_TcVnKeyPoint | |
|
ipTrainKeyPoints |
Container with training Keypoints (i.e. keypoints of a source/input image) of type CTcVnContainer_Vector_TcVnKeyPoint | |
|
ipMatches |
Container with matches between query and train Keypoints (CTcVnContainer_Vector_TcVnDMatch). | |
|
ipQueryCoordinates |
Reference To ITcVnContainer |

|
ipTrainCoordinates |
Reference To ITcVnContainer |
Returns a container with the coordinates of keypoints from the training Keypoints that exist in ipMatches (CTcVnContainer_Vector_TcVnPoint2_REAL) |
|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
