Detailed Description

template<typename T, class Tstate = bbstate_idx<T>>
class ebl::resize_module< T, Tstate >

Resize the input to the desired output (not preserving aspect ratio by default, see 'preserve_ratio' parameter).

Constructor & Destructor Documentation

template<typename T , class Tstate >

ebl::resize_module< T, Tstate >::resize_module	(	double	hratio,
		double	wratio,
		uint	mode = BILINEAR_RESIZE,
		uint	hzpad = 0,
		uint	wzpad = 0,
		bool	preserve_ratio = false
	)

This constructor specifies resizing ratio for each dimension instead of fixed target sizes. The default resizing method is bilinear, as as other methods do not currently implement ratio inputs.

Parameters:

height	target height for resizing.
width	target width for resizing.
mode	The type of resizing (MEAN_RESIZE, BILINEAR_RESIZE, GAUSSIAN_RESIZE).
hzpad	Optional vertical zero-padding is added on each size and taken into account to reach the desired target size.
wzpad	Optional horizontal zero-padding is added on each size and taken into account to reach the desired target size.
preserve_ratio	If true, fit the image into target size while keeping aspect ratio, eventual empty areas are filled with zeros.

template<typename T , class Tstate >

ebl::resize_module< T, Tstate >::resize_module	(	intg	height,
		intg	width,
		uint	mode = MEAN_RESIZE,
		uint	hzpad = 0,
		uint	wzpad = 0,
		bool	preserve_ratio = false
	)

Constructor.

Parameters:

height	target height for resizing.
width	target width for resizing.
mode	The type of resizing (MEAN_RESIZE, BILINEAR_RESIZE, GAUSSIAN_RESIZE).
hzpad	Optional vertical zero-padding is added on each size and taken into account to reach the desired target size.
wzpad	Optional horizontal zero-padding is added on each size and taken into account to reach the desired target size.
preserve_ratio	If true, fit the image into target size while keeping aspect ratio, eventual empty areas are filled with zeros.

template<typename T , class Tstate >

ebl::resize_module< T, Tstate >::resize_module	(	uint	mode = MEAN_RESIZE,
		uint	hzpad = 0,
		uint	wzpad = 0,
		bool	preserve_ratio = false
	)

Constructor without target dimensions. set_dimensions should be called later.

Parameters:

mode	The type of resizing (MEAN_RESIZE, BILINEAR_RESIZE, GAUSSIAN_RESIZE).
hzpad	Optional vertical zero-padding is added on each size and taken into account to reach the desired target size.
wzpad	Optional horizontal zero-padding is added on each size and taken into account to reach the desired target size.
preserve_ratio	If true, fit the image into target size while keeping aspect ratio, potential empty areas are filled with zeros.

template<typename T , class Tstate >

rect< int > ebl::resize_module< T, Tstate >::get_original_bbox

(

)

return the bounding box of the original input in the output coordinate system.

template<typename T , class Tstate >

void ebl::resize_module< T, Tstate >::set_input_region

(

const rect< int > &

inr

)

set the region to use in the input image. by default, the input region is the entire image.

template<typename T , class Tstate >

void ebl::resize_module< T, Tstate >::set_output_region

(

const rect< int > &

outr

)

set the region to use in the output image. by default, the output region is the entire size defined by set_dimensions().
