pure virtual |
Calculates a sparse optical flow.
| 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). |
