The flow of a hairdryer shown through the processing of Background Oriented Schlieren code created by Josh the Engineer, which allows us to see the air density gradient cause by the heating of the air. His code and guide is very interesting and informative, if you are interested check out his blog post here: https://www.joshtheengineer.com/2019/10/20/how-to-take-pictures-like-nasa-using-background-oriented-schlieren-bos

Mentioned this in critique, but I believe the term for the temperature gradient across a heating element like this is called a “Pattern Factor”. Hopefully that is useful for your report. Cool video!
Great video Xeen! I wonder how the video would have looked if you had decreased size of your search boxes or if you had used the interpolation feature more. I also like how you included the original color portion of the video at the beginning rather than just the black and white version.
