I AM TRYING TO WRITE A SOFTWARE THAT DETECTS THE TEMPERATURE VALUES IN THE IMAGE IN DEGREES WHEN A COMPUTER MOUSE LOOKS OVER THE THERMAL CAMERA IMAGE. HOW CAN I WRITE THIS?

Nope, not really, never used one other than with a vendor-supplied toolset, and that was only a one-time exercise at a power plant monitoring/finding hotspots on the boiler.
Bth, here's bound to be documentation for whatever product you're using -- I don't know if there's an industry standard that's followed or not.
Research is part of a project scope, not passing off the work to somebody else...

See attached demo. Adapt as needed to your image.

No, that is an uncalibrated color bar showing the relationship between array values and colors. No temperature calibration is implied by that image.
We cannot conclude anything about temperature. By convention, lowest data values would normally be at the bottom of the color bar, but obviously not in this case. Is it possible that blue corresponds to hotter? It is not impossible.
If you look at the DIAS example that Image Analyst posted then it shows the same colors and blue at the bottom is associated with the lowest temperature, so the only calibrated example we have here would have blue be cooler and red be hotter. But if you remember physics, "red hot" is the coolest temperature that emits visible light, and the hottest that emits visible light is far blue. Hotter is bluer, ultraviolet is high energy in physics. So we cannot rule out blue being associated with hotter... but neither can we confirm it.
