Detailed Description

template<class I>
class oln::topo::inter_pixel::interpixel< I >

Inter pixel class.

This example give the node of the black connected component (bottom left).

 #include <ntg/int.hh>
 #include <oln/basics2d.hh>
 #include <oln/topo/inter-pixel/inter-pixel.hh>
 #include <iostream>
 using namespace oln::topo::inter_pixel;

 int main()
 {
   typedef oln::image2d<ntg::int_u8> img_type;
   img_type in = oln::load(IMG_IN "test-cmap.pgm");
   interpixel<oln::image2d<ntg::int_u8> > ip(in);
   std::cout << ip << std::endl;
   // Print:
   //  (5,0): east north south
   //  (5,5): north west south
   //  (7,5): east north west
   //  (10,9): east north west
   //  (10,11): north west south
   //  (11,14): north west south
 }

Todo:

FIXME: Test the output values in the tests.
