Detailed Description

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

Energy of the gradient.

The snake should follow the edge of the object. The higher the gradient is, the less the energy is.

Definition at line 133 of file energies.hh.

Member Function Documentation

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

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 >.
