hi
i try to use Watershed Transform to separate touching objects
i read The Watershed Transform: Strategies for Image Segmentation
By Steve Eddins, MathWorks
www.mathworks.com/.../the-watershed-transform-strate...
i follow exact his code as below but no result i get
i think their a basic error in code
------------generate toching object-------
center1 = -10;
center2 = -center1;
dist = sqrt(2*(2*center1)^2);
radius = dist/2 * 1.4;
lims = [floor(center1-1.2*radius) ceil(center2+1.2*radius)];
[x,y] = meshgrid(lims(1):lims(2));
bw1 = sqrt((x-center1).^2 + (y-center1).^2) <= radius;
bw2 = sqrt((x-center2).^2 + (y-center2).^2) <= radius;
bw = bw1 | bw2;
imshow(bw), title('bw');
%----------------separate object------------
D = ~bwdist(~bw);
L=watershed(D);
BW(L == 0) = 0;
imshow(BW);
%-------------------------------------------
title('Distance transform of ~bw')

Should BW be bw?

You've got a few steps wrong, and are missing a few in the middle.
doc watershed - example 1 has basically the same code and works for me. You should just be able to copy and paste to replicate. If you have an older version of Matlab, you can find it on the web: http://www.mathworks.com/help/images/ref/watershed.html
