Sebastian,
  A trick that might help is to split the image into three color channels, then divide the green channel by the red one with 32bit result.  The brown regions should be easier to segment.

Regards,

Hi,
I've got difficulties selecting the brown color from this image using color threshold.
Do you know if there is a special filter for brown (DAB) or do you have a tip ??

thanks
