I am having troubles doing some image processing, and I am looking for a better coder than I to see if they're up to the challenge.

What I'm trying to do is measure the width of loose noodles in a picture, and get a histogram of the widths found. I've been trying to use edge detection and a whole lot of for loops, but realized my code only works if the edge detects a perfect square (because my code just looks diagonally). I'll attach my code, but I doubt it will be helpful. BW is a edge('gray image') logical.

 dist=0.*(1:300);
for x=1:300
    for y=1:300
        if BW(x,y)
            true;
            for i=1:(301-x-y)
                if BW(x+i,y+i)
                    true;
                    dist(x)=i;
                break
                else
                end
            end
        end
    end
end
