I am pursuing my masters degree in Computer science and engineering. I would like to know some challenges faced in thermal image processing using matlab. This would help me to find my project topic which could be done with the help of MATLAB.
So, what are the recent challenges in thermal image processing field.

Go here: http://www.visionbib.com/bibliography/keyword/indext.html and click on the thermal links and look at the papers that are being published to see what the current "hot" topics (sorry for the pun) in thermal analysis are.

Hello!
I m working on Thermal images to detect hotspot I.e; temperature above the thresold(standard) value. I have both RGB and GRAY scale image data set in jpg format of Transformer. I have software VIEWIR where i can see the temprature value corresponding to each pixel.. But i want to detect the hotspot..So can you please help me with some code to detect hotspot.
Thank you..

What does "detect" mean exactly? You could threshold the gray scale image and then measure various properties about it, like location, size, brightness etc. But I have no idea what you want.

Thanks for your reply..
I want to know if there is any hotspot or fault due to overheat(by continuously working) in thermal image or not.. like i have set of images and i require code to implement on images to localisation of extreme temperature area .. hope i m clear now..

Try this
% Find pixels that are hotter than some threshold value
hotPixelImage = thermalImage > someTemperature; % You pick what someTemerature is.
props = regionprops(hotPixelImage, thermalImage, 'Centroid', 'PixelList');
If length(props) >= 1 then there is a hot spot.
length(props) is the number of hot spots in the image.

Yes.. i tried to understand the image segmentation tutorial but there's one problem that i cant show the histogram of the image it is showing error continuously..n as you said i have original image copied directly by Thermal imaging camera.. how can i proceed??

Okay i m able to get histogram now.. but there's one more problem when i m processing my image instead of that coin image it is showing file not found.. how can i apply script on my images??

Please post your script and image in a new question instead of here in Freceena's question and I'll help you there.
