Functions
template<class T>
T	vil_greyscale_dilate (const T *im, const vcl_ptrdiff_t *offset, unsigned n)
	Return maximum value of im[offset[k]].
template<class T>
T	vil_greyscale_dilate (const vil_image_view< T > &image, unsigned plane, const vil_structuring_element &element, int i0, int j0)
	Return max of pixels under structuring element centred at (i0,j0).
template<class T>
void	vil_greyscale_dilate (const vil_image_view< T > &src_image, vil_image_view< T > &dest_image, const vil_structuring_element &element)
	Dilates src_image to produce dest_image (assumed single plane).

Function Documentation

template<class T>

void vil_greyscale_dilate	(	const vil_image_view< T > &	src_image,
		vil_image_view< T > &	dest_image,
		const vil_structuring_element &	element
	)

Dilates src_image to produce dest_image (assumed single plane).

dest_image(i0,j0) is the maximum value of the pixels under the structuring element when it is centred on src_image(i0,j0)

template<class T>

T vil_greyscale_dilate	(	const vil_image_view< T > &	image,
		unsigned	plane,
		const vil_structuring_element &	element,
		int	i0,
		int	j0
	)			[inline]

Return max of pixels under structuring element centred at (i0,j0).

Checks boundary overlap. Returns 0 if structuring element is empty.
