Segmentation problem

[Posthume]

Hi to all,

I'm a beginner in imagej and i'm facing some problems in segmenting some not easy pictures (below)










I'm supposed to characterize each rays by counting the cells inside them. I converted my pictures into 8 bits then binarised them with an entropy threshold and substracted the background (15 pixels) then analysed the particules after a watershed but it seems like everytime i get an over-segmentation.
Anyone has a better idea on how to segment such pictures please?

Any help would be appreciated.
Regards.
Mike.

Sorry for the link, it didn't seem to work. Just fixed the attached pictures now.
