vil_greyscale_erode() [3/3]

template<class T >

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

Erodes src_image to produce dest_image (assumed single plane).

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

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