Thermal imaging and image processing

The goal was to research the abilities of thermal imaging and image processing and look in the possibilities for non-destructive testing. The goal was to identify the holes in the specimen while the photos were taken from a side which the holes are not visible from. In this case the holes were supposed to be detected but it could also be cracks and/or other errors in the part. The gradient function is to look at the way the heat moves out of the part after it is heated.
