Detailed Description

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

Same as resizepp_module, except that it replicates the output at different scales.

Constructor & Destructor Documentation

template<typename T , class Tstate >

ebl::fovea_module< T, Tstate >::fovea_module	(	std::vector< double > &	fovea,
		midxdim &	fovea_scales_size,
		idxdim &	dsize,
		bool	boxscale = false,
		uint	mode = MEAN_RESIZE,
		module_1_1< T, Tstate > *	pp = NULL,
		bool	own_pp = true,
		idxdim *	dzpad = NULL,
		const char *	name = "fovea"
	)

Constructor. Preprocessing module pp will be deleted upon destruction.

Parameters:

boxscale	If true, rescale input box by fovea factors and input is unchanged, otherwise resize input by 1/(fovea factors) and box is unchanged. Box scaling should be used for training extraction and image scaling for detection (default is false).
pp	An optional pointer to a preprocessing module. If NULL, no preprocessing is performed. This module is responsible for destroying the preprocessing module.
mode	The type of resizing (MEAN_RESIZE, BILINEAR_RESIZE, GAUSSIAN_RESIZE).
size	The target dimensions (heightxwidth)
zpad	Optional zero-padding is added on each side

template<typename T , class Tstate >

ebl::fovea_module< T, Tstate >::fovea_module	(	std::vector< double > &	fovea,
		bool	boxscale = false,
		uint	mode = MEAN_RESIZE,
		module_1_1< T, Tstate > *	pp = NULL,
		bool	own_pp = true,
		idxdim *	dzpad = NULL,
		const char *	name = "fovea"
	)

Constructor without target dimensions. set_dimensions should be called later. Preprocessing module pp will be deleted upon destruction.

Parameters:

boxscale	If true, rescale input box by fovea factors and input is unchanged, otherwise resize input by 1/(fovea factors) and box is unchanged. Box scaling should be used for training extraction and image scaling for detection (default is false).
pp	An optional pointer to a preprocessing module. If NULL, no preprocessing is performed. This module is responsible for destroying the preprocessing module.
mode	The type of resizing (MEAN_RESIZE, BILINEAR_RESIZE, GAUSSIAN_RESIZE).
zpad	Optional zero-padding is added on each side
