Detailed Description

template<typename N>
struct mln::topo::is_simple_2d_t< N >

Test if a point is simple or not.

A point of an object is simple if in its c8 neiborhood, there is exactly one connected component of the object, and only one connected component of the background Examples : ( | == object, - = background)

• - | | P | Here p is simple in the c4 and c8 case. | | |

• | - | P | Here p is never simple. | | |
