Good evening,

How to extract the area of the coloured section (jet area) and the smallest diameter of the jet area?

Well, for this homework task you'll get a hint:
In the gray-scale area the R, G and B-layers of your image all have the same values.

No, my idea was for you to look for pixels where the intensities in the R G and B layers were not identical. Something like:
R = rgb_img(:,:,1);
G = rgb_img(:,:,2);
B = rgb_img(:,:,3);
gray_img = (R==B)&(G==R);
jet_img = 1-gray_img;
ought to give you a binary image jet_img with 1 in the jet-coloured region and 0 in the gray-scale region.
