Detailed Description

Structuring element for 3D morphology represented as a list of non-zero pixels.

Function Documentation

vcl_ostream& operator<<	(	vcl_ostream &	,
		const vil3d_structuring_element &	element
	)

Write details to stream.

void vil3d_compute_offsets	(	vcl_vector< vcl_ptrdiff_t > &	offset,
		const vil3d_structuring_element &	element,
		vcl_ptrdiff_t	istep,
		vcl_ptrdiff_t	jstep,
		vcl_ptrdiff_t	kstep
	)

Generate a list of offsets for use on image with istep,jstep.

On exit offset[a] = element.p_i()[a]*istep + element.p_j()[a]*jstep + element.p_k()[a]*kstep

Gives an efficient way of looping through all the pixels in the structuring element
