Day 16 - more code

Today i added to my original program to make it so the user can now input the values by clicking on a b-scan. These values are then used to focus the data to the most important part, this includes removing air and other noise and looking at just the echo from the paper. In my down time today i tried to learn more about the Hilbert transform, because i didn't understand Maria's explanation even though it was very well done. It is hard to teach linear algebra concepts to a kid who has not even taken calculus. Monday I will hopefully fix this program and begin focusing all of our data so we can analyze it for the rest of the week and begin sending information to Portugal.
