filter colours from a multicolour Image using ImageJ

Vivek Saraswat
Hi,

I have been working on to separate particles of different colours in a
image using ImageJ. So the standard procedure is to use HSB stack or RGB
stack to separate the colours, then threshold them after converting them to
binary.

However, because I have continuum of colours in my image, (like Red, Dark
Orange are almost alike et al.) for clear separation, I first convert the
RGB image to 8 bit Color image containing just 6 colours. This way I have
just 6 RGB values in the image and I save those values in a excel sheet
using LUT. Now, I convert this image back to RGB, so that I can threshold
it with the new 6 RGB values (The image will now have six and only six
colours). But, now I am unable to find a command that can help me import
those RGB values from Excel Sheet and apply them directly.

I actually have about 200 images, so cant do this manually; have to do it
using a macro.

So is there any command, which can help me to directly import those RGB
values from excel sheet, and apply it on the image?


Regards,

Vivek
