function [gradient, or] = canny(im, sigma, scaling, vert, horz)
xscaling = vert; yscaling = horz;
hsize = [6*sigma+1, 6*sigma+1]; % The filter size.
gaussian = fspecial('gaussian',hsize,sigma);
im = filter2(gaussian,im); % Smoothed image.
im = imresize(im, scaling, 'AntiAliasing',false);
[rows, cols] = size(im);

d2 = [ zeros(1,cols); im(1:rows-1,2:cols) zeros(rows-1,1); ] - ...
[ zeros(rows-1,1) im(2:rows,1:cols-1); zeros(1,cols) ];
X = ( h + (d1 + d2)/2.0 ) * xscaling;
Y = ( v + (d1 - d2)/2.0 ) * yscaling;
gradient = sqrt(X.*X + Y.*Y); % Gradient amplitude.
or = atan2(-Y, X); % Angles -pi to + pi.
neg = or<0; % Map angles to 0-pi.
or = or.*~neg + (or+pi).*neg;
or = or*180/pi; % Convert to degrees.
