Calculate divergence from flow vectors by looking at line sizes between the points.
Uses optical flow vectors as determined with a corner tracker and Lucas Kanade to estimate divergence.

Get divergence from optical flow vectors based on line sizes between corners.
[in] | vectors | The optical flow vectors |
[in] | count | The number of optical flow vectors |
[in] | n_samples | The number of line segments that will be taken into account. 0 means all line segments will be considered. |
