prev_pts: &dyn ToInputArray,
next_pts: &mut dyn ToInputOutputArray,
status: &mut dyn ToOutputArray,

) -> Result<()>
Calculates a sparse optical flow.
Parameters
- prevImg: First input image.
- nextImg: Second input image of the same size and the same type as prevImg.
- prevPts: Vector of 2D points for which the flow needs to be found.
- nextPts: Output vector of 2D points containing the calculated new positions of input features in the second image.
- status: Output status vector. Each element of the vector is set to 1 if the flow for the corresponding features has been found. Otherwise, it is set to 0.
- err: Optional output vector that contains error response for each point (inverse confidence).
- stream: Stream for the asynchronous version.
C++ default parameters
- err: cv::noArray()
- stream: Stream::Null()
