\brief 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).
