Function Documentation

void mmn_get_order	(	unsigned	v0,
		unsigned	v1,
		unsigned	v2,
		unsigned &	i0,
		unsigned &	i1,
		unsigned &	i2
	)

(i0,i1,i2) gives ordering of v0,v1,v2.

Each i is {0,1,2}, indicating rank of equivalent v ie if i0=1, then v0 is the middle value if i1=2, then v1 is the largest value

void mmn_get_rank	(	unsigned	v0,
		unsigned	v1,
		unsigned	v2,
		unsigned &	i0,
		unsigned &	i1,
		unsigned &	i2
	)

(i0,i1,i2) gives rank of v0,v1,v2.

I.e. v[i0] is smallest, v[i2] is largest

vil_image_view<double> mmn_order_cost	(	const vil_image_view< double > &	c,
		unsigned	v1,
		unsigned	v2,
		unsigned	v3
	)

Create new view of data, with axes re-arranged.

c(i1,i2,i3) is the value associated with i1 on node v1, i2 on node v2 etc. The i-axis of the returned image is associated with the node min(v1,v2,v3), the j axis with mid(v1,v2,v3) and the k with max(v1,v2,v3) The inverse operation is given by mmn_unorder_cost

vil_image_view<double> mmn_unorder_cost	(	const vil_image_view< double > &	c,
		unsigned	v1,
		unsigned	v2,
		unsigned	v3
	)

Make new view of data, with axes re-arranged. Inverse of mmn_order_data.

Make new view of data, with axes re-arranged. Inverse of mmn_order_cost.

The i-axis of c is associated with the node min(v1,v2,v3), the j axis with mid(v1,v2,v3) and the k with max(v1,v2,v3) Returns image r, where r(i1,i2,i3) is the value associated with i1 on node v1, i2 on node v2 etc.
