|---|---|---|
 | AlgorithmPtr |
Return the pointer to the algorithm object
(Inherited from IAlgorithm.) |
| NvidiaOpticalFlowPtr |
Pointer the the native cv::cuda::NvidiaOpticalFlow object.

Calculates Optical Flow using NVIDIA Optical Flow SDK.
NVIDIA GPUs starting with Turing contain a dedicated hardware accelerator for computing optical flow vectors between pairs of images.
The optical flow hardware accelerator generates block-based optical flow vectors.
The size of the block depends on hardware in use, and can be queried using the function getGridSize().
The block-based flow vectors generated by the hardware can be converted to dense representation(i.e.per-pixel flow vectors) using upSampler() helper function, if needed.
The flow vectors are stored in CV_16SC2 format with x and y components of each flow vector in 16-bit signed fixed point representation S10.5.

| Clear |
Clear the algorithm

| GetDefaultName |
Returns the algorithm string identifier.
This string is used as top level xml/yml node tag when the object is saved to a file or string.
(Defined by AlgorithmExtensions.) |
| IsEmpty |
Returns true if the Algorithm is empty. e.g. in the very beginning or after unsuccessful read.
(Defined by AlgorithmExtensions.) |
| Load |
Loads algorithm from the file
(Defined by AlgorithmExtensions.) |
| LoadFromString |
Loads algorithm from a String
(Defined by AlgorithmExtensions.) |
| Read |
Reads algorithm parameters from a file storage.
(Defined by AlgorithmExtensions.) |
| Save |
Save the algorithm to file
(Defined by AlgorithmExtensions.) |
| SaveToString |
