MATLAB: How to detect the temperature degrees from a thermal image taken by Therm App camera

genetic algorithmimage processingimage segmentation

Hello,

I would like to ask about how can i use matlab to detect the temperature out from a thermal image taken by themapp camera. I converted the thermal image to greyscaled image, plus i applied Adaptive thresholding for it. Looking for help.

Thanks

"I converted the thermal image to greyscaled image" <= well there's your problem. DON'T DO THAT. Keep the thermal image as it is, with units of temperature as given by your instrument. DO NOT convert units to gray levels. Keep your thermal image unconverted and you'll have the proper units or Kelvin or Celcius or whatever.

You need to analyze the original grayscale image, not the rgb pseudocolored image. To verify you should look at pixel values and compare the intensity at that location with the temp measured with another device, like a thermometer, and use on individuals known to have, or not have, fever.

To apply pseudocolors, use the colormap() function. There are a variety of built-in colormaps you can choose from, in addition to building your own custom colormap.

[pixelCounts, grayLevels] = imhist(grayImage);
[maxCount, indexOfMax] = max(pixelCounts);
grayLevelAtMax = grayLevels(indexOfMax);
