Error Concealment | JPEG | MPEG-4 | Wavelet | YUV

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.

Regards,
Kumar

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.

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