My attached demo can do that. Adapt it to your image by specifying where your colormap is located, and the limits (-10.5 to 29) of your color bar range.

My demo doesn't segment the image. This demo converts the pseudocolored image into a thermal image with units of temperature. This is a necessity before segmentation can take place. Segmentation can then take place using whatever method works, like thresholding, texture analysis, or whatever.
