Detailed Description

template<class I>
class oln::snakes::continuity_energy< I >

Energy of continuity.

The goal of this energy is to avoid pack of nodes an lack of nodes in some part of the snake. The average distance between two consecutive points is average_dist. The more the distance between prev and current is far from average_dist, the higher the energy is.

Member Function Documentation

template<class I>
ntg::float_s oln::snakes::continuity_energy< I >::compute (  const I &  ,
const node< I > &  prev,
const node< I > &  current,
const node< I > & 
)  [inline]
 

Return the energy.

The first arg is the gradient of the image; the 3 nodes are the previous, the current and the next node.

Reimplemented from oln::snakes::energy< I >.
