Detailed Description

template<typename InputDataType = arma::mat, typename OutputDataType = arma::mat>
class mlpack::ann::Glimpse< InputDataType, OutputDataType >

The glimpse layer returns a retina-like representation (down-scaled cropped images) of increasing scale around a given location in a given image.

Template Parameters

InputDataType	Type of the input data (arma::colvec, arma::mat, arma::sp_mat or arma::cube).
OutputDataType	Type of the output data (arma::colvec, arma::mat, arma::sp_mat or arma::cube).

Definition at line 88 of file glimpse.hpp.

Constructor & Destructor Documentation

Glimpse	(	const size_t	inSize = 0,
		const size_t	size = 0,
		const size_t	depth = 3,
		const size_t	scale = 2,
		const size_t	inputWidth = 0,
		const size_t	inputHeight = 0
	)

Create the GlimpseLayer object using the specified ratio and rescale parameter.

Parameters

inSize	The size of the input units.
size	The used glimpse size (height = width).
depth	The number of patches to crop per glimpse.
scale	The scaling factor used to create the increasing retina-like representation.
inputWidth	The input width of the given input data.
inputHeight	The input height of the given input data.
