As mentioned earlier, the Cinetermografia is an application of thermography . And thermography is nothing but recording through a camera, the temperature of what is observed. It all seems very simple, so. In reality, problems arise when there is a need to apply thermography of moving subjects, and especially of living beings, which by their nature are subject quite unpredictable. To obtain graphs
thermography (excuse the pun) should be able to record the thermal evolution of a point (or area) over time. If that point (area) is stationary, it is easy to monitor it. But when that point is moving, that's the trouble: must be able to "follow".
Follow a point is a little 'how to follow a person. If the person is alone, it's easy. A person in a crowd, however, will merge with the people around you. And finally, you might realize you have stalked the wrong person. We must give that person a flag, a bit 'as they do the tourist hordes. In the case thermography, the "flag" is the temperature difference between a point and its neighbors. Following these differences (which in reality are not simply between a point and those around him, but also those around him and those around those around him and so on, try to think of an onion), in the end we will find itself in our hands the point concerned. It will be done. For
area, the question is obviously more complex. But the underlying principles are the same.
You should know that there is no software that can do such a thing, in thermography. Or rather, there now is in production at the School of Computer Science. So soon you will see graphs of your temperature, if you attended the screenings.
Ah, the next will be Tuesday, December 9 at 21:00 . The film screened (which I liked very much, NDT), Lunch will be mid-August. See you at Space
Oberdan!
