Hello France,

What kind of segmentation algorithm did you use? The easiest I am thinking
is a k-means clustering.

You can try different colour spaces. HSB is straight forward.
Image->Type->HSB Stack.

There are another two diffent colour space transformation in the plugins
page: http://rsb.info.nih.gov/ij/plugins/index.html#color
These are Luv and Lab. Try that and see if the results improve.

Another thing is that you could send me an image to see it so I can have a
better idea of the kind of images you are working with.

Kind regards,

Maria
