How to convert Temperature maps into rgb images

I am using satellite derived temperature values and I want to convert them to rgb so that I can perform superpixels clustering. I am trying to have the rgb values for each pixel (of the colormap). What do you suggest me to do?

This should work

n = 100;                                         % number of colors
mycolor = jet(n);                                % create a colormap
index = interp1([Tmin Tmax],[1 n],Tcur);         % get index for current temperature
index = round(index);
mycolor(index,:)                                 % color of a pixel

Let me know if it doesn't work

That made me laugh. As of now, you only need 88,066 more points until you're the best. Of course, when you're at 88,642 rep, Walter may have hit the 100,000.

Come on Darova, no need to start flagging. You invited such a comment with your remark. If you strive for the top number of reputation points you will also find threads like this one about you in due course: Is Walter Roberson a real person, or is he some kind of Matlab AI robot?

Not offence was meant at all. I just found it funny considering that none of us stand a chance of ever catching Walter, Image Analyst, Star Strider or even Jan. So you have your work cut out if you want to reach the top of the leaderboard.

On the other hand, begging for votes (it's not the first time if I recall) is going to rub people the wrong way. Let your contributions stand on their own merit.

GUys, i just do my best

no offense

I only earned about 1 1/4 points per hour over the last month. Only about 40% of my Answers get Accepted. I am getting older and will not be around forever. Someone will catch up some day.

Well Walter, unless you can continue from the afterlife, to stay in the lead you'd better get to work on that AI answerer robot that can answer posts automatically long after you're gone.
