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.

float get_size_divergence  (  struct flow_t *  vectors, 
int  count,  
int  n_samples  
) 
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.
