Detailed Description

template<typename L>
struct mln::accu::count_labels< L >

Count the number of different labels in an image.

The parameter L is the label type to be count.

Constructor & Destructor Documentation

template<typename L>
mln::accu::count_labels< L >::count_labels ( )

Member Function Documentation

template<typename L>
void mln::accu::count_labels< L >::init ( )

Manipulators.

template<typename L>
bool mln::accu::count_labels< L >::is_valid ( ) const

Check whether this accu is able to return a result.

Always true here.

template<typename L>
void mln::accu::count_labels< L >::set_value ( unsigned  c)

Force the value of the counter to c.

template<typename L>
void mln::accu::count_labels< L >::take ( const count_labels< L > &  other)
void mln::Accumulator< count_labels< L > >::take_as_init ( const T t)
inherited

Take as initialization the value t.

void mln::Accumulator< count_labels< L > >::take_as_init_ ( const T t)
inherited

INTERNAL_API

Default implementation of "take as initialization".

void mln::Accumulator< count_labels< L > >::take_n_times ( unsigned  n,
const T t 
)
inherited

Take n times the value t.

void mln::Accumulator< count_labels< L > >::take_n_times_ ( unsigned  n,
const T t 
)
inherited

INTERNAL_API

Default implementation of "take n times".

template<typename L>
unsigned mln::accu::count_labels< L >::to_result ( ) const

Get the value of the accumulator.
