Detailed Description

template<typename I>
class mln::labeled_image< I >

Morpher providing an improved interface for labeled image.

Template Parameters:

I

The label image type.

This image type allows to access every site set at a given label.

This image type guaranties that labels are contiguous (from 1 to n).

template<typename I, typename E>

const util::array< typename labeled_image_base< I, E >::bbox_t > & mln::labeled_image_base< I, E >::bboxes

(

)

const [inline, inherited]

Return the component bounding boxes.

Referenced by mln::labeled_image< I >::labeled_image().

template<typename I, typename E>

const [inline, inherited]

Return the number of labels;.

template<typename I, typename E>

template<typename F>

void mln::labeled_image_base< I, E >::relabel
