Constructor & Destructor Documentation

template<class DataType, class IIDataType >

pcl::IntegralImage2D< DataType, IIDataType >::IntegralImage2D	(	DataType *	data,
		const int	width,
		const int	height,
		const int	dimensions,
		const bool	compute_second_order_integral_images,
		const int	element_stride,
		const int	row_stride
	)

Constructor.

Internally creates the integral images.

Parameters:

data	the dense 2d input data array.
width	the width of the 2d input data array.
height	the height of the 2d input data array.
dimensions	number of dimensions of each element.
compute_second_order_integral_images	whether to compute second order integral images.
element_stride	number of DataType entries per element (equal or bigger than dimensions).
row_stride	number of DataType entries per row (equal or bigger than element_stride * number of elements per row).
