void draw_tree	(	vil_image_view< vxl_byte > &	image,
		const vcl_vector< vgl_point_2d< double > > &	pts,
		const vcl_vector< vcl_pair< int, int > > &	pairs
	)

Definition at line 260 of file fhs_match_tree_model.cxx.

void extract_normalised_patches	(	const vimt_image &	image,
		const vcl_vector< vgl_point_2d< double > > &	pts,
		int	half_width,
		vcl_vector< vil_image_view< float > > &	patch,
		vcl_vector< vgl_point_2d< double > > &	ref_pts
	)

Sample normalised patches around each point.

Extract patches with given half-width around each pts[i] When near an image edge, patch may be truncated ref_pts defines position of original point relative to the patch origin

bool fhs_load_arcs	(	const vcl_string &	path,
		vcl_vector< vcl_pair< int, int > > &	pairs
	)

Load in pairs of indices indicating connections between points.

File format: Each line contains two integers

bool fhs_load_points	(	const vcl_string &	path,
		vcl_vector< vgl_point_2d< double > > &	pts
	)

Load in points in ISBE points format.

eg: n_points: 12 { 1 2 3 4 .... }

void vimt_resample	(	const vimt_image_2d_of< float > &	src_im,
		int	src_L,
		vimt_image_2d_of< float > &	dest_im,
		int	dest_L
	)

Generate a new image with resolution suitable for dest_L.

Requires dest_L>src_L, else dest_im is a (shallow) copy of src_im
