Stuff to Learn

Prior to today, I didn't think the following was possible. What does this have to do with econometrics? I was never that interested in maximum entropy estimation and I don't know much about it, but the following image is maximum entropy applied to image data. Now I'm interested.

The following fact by way of Mario Juric:

While most people can see with a resolution of 1?€™, the image on our retina is blurred through a PSF of width as large as 5?€™ due to various effects (the largest being chromatic aberration).

And while we still struggle with finding optimal deconvolution algorithms, the brain happily performs the procedure on a 8500x5400 (43Mpix) image, a few times per second, ~17 hours a day, 365 days a year.
