Color area

[Marco Coan]

Hello to everybody,
does anyone know the way to measure the percentage of different colors
(or different areas) in a rgb image? I'm working on food (meat
particularly) and i'm trying to discriminate the different oxydation
state in a beef slice. Thank you.

You can use the 3D Color Inspector plugin
http://rsb.info.nih.gov/ij/plugins/color-inspector.html
Use the histogram or color quantization mode and press on the LUT button.

>Hi,

The color area is the number of pixels having the specified value RGB
So you can simply check the color histogram.
Can you specify your question?

regards
