you may also try watershed segmentation. you can find more information
in matlab help file.

A hough transform might do the trick, although I understand it requires a fair
amount of processing. The shape you're looking for needs to be expressed
parametrically then a lot of different combinations of the parameters are tested
against your thresholded image. A maximum will occur where your object is even
with breaks in the circle.
Hope that helps,
Mike.

Hi All,
I am working on Cell Segmentation for the detection of cancer cells.
The cells are separated from the background using a threshold. Later form factor
is used to separate the circular cells from the rest of the non-circular regions
in the image. However, some of the cells go undetected as there are a couple of
pixels missing to form the complete circular shape. So I wanted to use a
circular template to detect the cell regions. Could some one help me with the
MATLAB code for this. It is a little urgent,so any help is appreciated! Thanks
in advance.
