My research has been reduced to the cheshire cat.

I have been messing around with my images to gain a better understanding of how they are analyzed. I analyze them for position of the spheres as they pass through the water. Knowing the position helps me determine the spin rate of the spheres. To get the position data I simply subtract two consecutive images, throw out the points that are gray, and look for the perimeter of the remaining blob. I then match the perimeter to the curve of my ball and I know the center. I got to a certain point and noticed that I had recreated the Cheshire Cat! I couldn't stop laughing. Yes I am a nerd.
