# vision research, 1 minutes

Graphed 17 catches of 7 ball cascade: https://drive.google.com/open?id=0B7QqDexrxSfwZUhKamliLVJ2Ykk

I recorded this in 480p@120fps. The tracking program does much better at higher frame rates or lower resolutions. It is counter-intuitive that it would work better at lower resolution. This is the best data that I have produced.

This is also the fourth framerate that I have used; 30, 48, 60, and now 120 frames per second. The data doesn't work well for comparative purposes if the frame rates are different.

I have made some improvements to my tracking program, and am currently working on applying a Kalman filter. Kalman filters are rocket-science level confusing. Literally; Kalman filters were developed for the Apollo program to help land on the moon.

Going forward, the best path is to write a better tracking program, and the re-record the juggling data in 120fps.

Total practice time: 1 minutes
