Detailed Description
template<typename PointInT>
class pcl::tracking::HSVColorCoherence< PointInT >
HSVColorCoherence computes coherence between the two points from the color difference between them.
the color difference is calculated in HSV color space. the coherence is calculated by 1 / ( 1 + w * (w_h^2 * h_diff^2 + w_s^2 * s_diff^2 + w_v^2
- v_diff^2))
