I am trying to implant Canny Edge Detection algorithm.
I started first with decomposing it using matlab functions.
function [newImg, tgTeta] = edgeDetectMatlab(img)
newImg=zeros(size(img));
tgTeta=zeros(size(img));
smoothImg=imgaussfilt(img,1.4);
[fx,fy]=imgradientxy(img);
tgTeta=imgradient(img);
end
I know that 2 steps are missing: non-maximum suppression and double threshold, but how can I do an non-maximum suppression?

There is a Canny method in the edge() function. Why not use that?
