Creates an instance of PCAFlow algorithm.
- Parameters
-
_prior | Learned prior or no prior (default). |
- See also
- cv::optflow::PCAPrior
- Parameters
-
_basisSize | Number of basis vectors. |
_sparseRate | Controls density of sparse matches. |
_retainedCornersFraction | Retained corners fraction. |
_occlusionsThreshold | Occlusion threshold. |
_dampingFactor | Regularization term for solving least-squares. It is not related to the prior regularization. |
_claheClip | Clip parameter for CLAHE. |
§ calc()
Calculates an optical flow.
- Parameters
-
I0 | first 8-bit single-channel input image. |
I1 | second input image of the same size and the same type as prev. |
flow | computed flow image that has the same size as prev and type CV_32FC2. |
Implements cv::DenseOpticalFlow.
