template<typename I, typename O>

void mln::data::abs	(	const Image< I > &	input,
		Image< O > &	output
	)			[inline]

Apply the absolute value (abs) function to image pixel values.

Parameters:

[in]	input	The input image.
[out]	output	The output image.

Definition at line 68 of file data/abs.hh.

References mln::trace::entering(), mln::exact(), mln::trace::exiting(), and transform().

template<typename I>

void mln::data::abs_inplace

(

Image< I > &

input

)

[inline]

Apply the absolute value (abs) function to image pixel values.

Parameters:

[in,out]

input

The input image.

Definition at line 80 of file data/abs.hh.

References apply(), mln::trace::entering(), mln::exact(), and mln::trace::exiting().

template<typename I, typename F>

void mln::data::apply	(	Image< I > &	input,
		const Function_v2v< F > &	f
	)			[inline]

Apply a function-object to the image input.

Parameters:

[in,out]	input	The input image.
[in]	f	The function-object.

This routine runs:
for all p of input, input(p) = f( input(p) )

This routine is equivalent to data::tranform(input, f, input) but it is faster since a single iterator is required.

Todo:

Add versions for lowq images.

	)			[inline]

Generic implementation of data::transform.

Transform two images input1 input2 through a function f.

Parameters:

[in]	input1	The 1st input image.
[in]	input2	The 2nd input image.

This routine runs:
for all p of input, output(p) = f( input1(p), input2(p) ).

Parameters:

[in]	input1_	The 1st input image.
[in]	input2_	The 2nd input image.
[in]	f_	The function.
