Regarding the watershed transform.

This is my input Image Input Image
I want to seperate the individual chromosomes from this image. I have used watershed transformation. I got the output as Output Image.
Is there any possibilty to seperate the regions of chromosomes from here???
My code is
inputImage = imread('chromosome.jpg');
figure, imshow(inputImage);
bw = im2bw(inputImage,0.8);
figure, imshow(bw), title('bw')
D = bwdist(~bw);
figure, imshow(D);
title('Distance transform of ~bw')
D = -D;
D(~bw) = -Inf;
L = watershed(D);
rgb = label2rgb(L,'spring');
figure, imshow(rgb);
title('Watershed transform of D');

What does that mean? Watershed does separate them and give you a labeled image. So what's the problem? http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

My problem is to seperate the individual chromosome images in there. The process is called chromosome karyotyping

If watershed is not doing the job for you then you need to use an algorithm that people have used successfully and published, like those in section 20.4 here: VisionBib
