int oriented_sum_sq_distance
(
	Edge_point const ***image_edge_map,
	int num_rows,
	int num_cols,
	const Edge_set *tmplate,
	int offset_row,

PARAMETERS

int num_rows
rows of image_edge_map
int num_cols
columns of image_edge_map
int offset_row
top of template
int offset_col
left edge of template
double *distance
output chamfer distance

DESCRIPTION

Compute the oriented sum-of-squares distance between an input image and an edge template, using distance metric described in Shotton, Blake, Cipolla 08. Image must be input as a matrix of Edge_point pointers to the nearest edge point at each position. This is output by chamfer_transform_2. num_rows and num_cols describes the size of image_edge_map Template must be input as an Edge_point linked list like that output by detect_edge_points. Offset_{x,y} is the position of the top-left of the template. Distance_out is the computed chamfer distance.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
