@param inputImage Input image.
@param referenceImage Reference image of the same size and the same type as input image.
@param flow A buffer consisting of inputImage.Size() / getGridSize() flow vectors in CV_16SC2 format.
@param stream Stream for the asynchronous version.
@param stream It is highly recommended that CUDA streams for pre and post processing of optical flow vectors should be set once per session in create() function as a part of optical flow session creation.
This parameter is left here for backward compatibility and may be removed in the future.
Default value is NULL stream;
@param hint Hint buffer if client provides external hints. Must have same size as flow buffer.
Caller can provide flow vectors as hints for optical flow calculation.
@param cost Cost buffer contains numbers indicating the confidence associated with each of the generated flow vectors.

@param enableExternalHints Optional Parameter. Flag to enable passing external hints buffer to calc(). Defaults to false.
@param enableCostBuffer Optional Parameter. Flag to enable cost buffer output from calc(). Defaults to false.
@param gpuId Optional parameter to select the GPU ID on which the optical flow should be computed. Useful in multi-GPU systems. Defaults to 0.
@param inputStream Optical flow algorithm may optionally involve cuda preprocessing on the input buffers.
The input cuda stream can be used to pipeline and synchronize the cuda preprocessing tasks with OF HW engine.
If input stream is not set, the execute function will use default stream which is NULL stream;
@param outputStream Optical flow algorithm may optionally involve cuda post processing on the output flow vectors.
The output cuda stream can be used to pipeline and synchronize the cuda post processing tasks with OF HW engine.
If output stream is not set, the execute function will use default stream which is NULL stream;
