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).

Member Function Documentation

template<typename I >

const labeled_image< I >::bbox_t & mln::labeled_image< I >::bbox

(

const typename I::value &

label

)

const [inline]

Return the bounding box of the component label.

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

template<typename I >

const util::array< typename labeled_image< I >::bbox_t > & mln::labeled_image< I >::bboxes

(

)

const [inline]

Return the component bounding boxes.

template<typename I >

I::value mln::labeled_image< I >::nlabels

(

)

const [inline]

Return the number of labels;.

template<typename I >

template<typename F >

void mln::labeled_image< I >::relabel

(

const Function_v2b< F > &

f

)

[inline]

Labels may be removed.

This overload make sure the labeling is still contiguous.

References mln::labeling::relabel_inplace().

template<typename I >

template<typename F >

void mln::labeled_image< I >::relabel

(

const Function_v2v< F > &

f

)

[inline]

Relabel according to a function.

Labels may be removed and the labeling may not be contiguous afterwards. FIXME: currently the labels are packed after relabeling for performance reasons. Do we want to be less restrictive?

pack_().

template<typename I >

p_if< mln_box(I), fun::eq_v2b_expr_< pw::value_< I >, pw::cst_< typename I::value > > > mln::labeled_image< I >::subdomain

(

const typename I::value &

label

)

const [inline]

Return the domain of the component with label label.
