Creating a colormap for an image

4 views (last 30 days)
Hi
I am trying to do a simulation of an infrared camera and what I need to do now is to create a color map. What I was suggested to do was to assign each colour from a visible band image a certain temperature and then work with the HSV. My coordinator suggested me something like 'hue value = temperature' and so on. And the function that helps me change them is this:
temperatureImage = minTemp + (maxTemp - minTemp)*image_h;
where 'image_h' is the hue value of the actual image. I was thinking of creating an if statement that will have HSV, but I don't know how to properly do that.
Can anyone suggest how to do that? I would much appreciate.
Thank you so much!

You will probably want to use something like a jet colormap. See this page for more details: https://nl.mathworks.com/help/matlab/ref/colormap.html
Then use caxis for implementing your minimum and maximum temperature limits https://nl.mathworks.com/help/matlab/ref/caxis.html
