Detailed Description

template<typename I>
struct mln::accu::shape::volume< I >

Volume accumulator class.

The parameter I is the image type on which the accumulator of pixels is built.

Member Typedef Documentation

template<typename I>

typedef util::pix<I> mln::accu::shape::volume< I >::argument

The accumulated data type.

The volume of component is represented by the volume of its root pixel. See mln::morpho::closing_volume and mln::morpho::opening_volume for actual uses of this accumulator. FIXME: Replaced by mln::morpho::attribute::volume

template<typename I>

typedef argument::value mln::accu::shape::volume< I >::value

The value type associated to the pixel type.

template<typename I>

void mln::accu::shape::volume< I >::init

(

)

[inline]

Manipulators.

template<typename I>

bool mln::accu::shape::volume< I >::is_valid

(

)

const [inline]

Check whether this accu is able to return a result.

Always true here.

template<typename I>

void mln::accu::shape::volume< I >::set_value

(

unsigned

v

)

[inline]

Force the value of the counter to v.

template<typename E>

template<typename T>

void mln::Accumulator< E >::take_as_init

(

const T &

t

)

[inline, inherited]

Take as initialization the value t.

Dev note: this is a final method; override if needed by take_as_init_ (ending with '_').

Reimplemented in mln::accu::stat::variance< T, S, R >.

template<typename E>

template<typename T>

void mln::Accumulator< E >::take_n_times	(	unsigned	n,
		const T &	t
	)			[inline, inherited]

Take n times the value t.

Dev note: this is a final method; override if needed by take_as_init_ (ending with '_').

template<typename I>

unsigned mln::accu::shape::volume< I >::to_result

(

)

const [inline]

Get the value of the accumulator.
