I am not sure if I should ask this question in this list. But I'll try.

Currently I am trying to analyze images using EBImage and biOps.
One of the features that I need to extract from various images is the color
spectrum, namely, which colors each image consists of.

So, each image hopefully can be converted into some sort of color histogram
so that color ingredients are easily comparable with each other.

There are so many functionalities that these packages and others provide,
and I am hoping that someone would give me some guideline for the analysis.

Any suggestion?

Thanks.
