I’ve been debating what to write for my next blog post for some time.  There have been a few inarticulate ideas kicking around, but nothing inspiring enough to get me in front of the computer.  Then, this morning, it hit me.  I’m thankful for so many things in my life — not in a Thanksgiving-I-am-thankful-for sort of way — but sincerely thankful that certain things in my life are the way they are.  Here is a list (open to tweaking) in no particular order.

Thank God…

1. I’m not married.
2. I don’t have a kid.
3. I have a mom and dad who love me.
4. I have great friends.
5. I’m a male.
6. I’m intelligent.
7. I’m creative.
8. I’m my own boss.
9. I went to college and graduated in 4 years.
10. I’m going to law school.
11. I’ve been to Ireland.
12. I’ve loved at least one person in my life.
13. I have my awesome car.
14. I’m not a virgin.
15. I have no disability.
16. I am able to run.
17. I am healthy.

19. Obama is our president.
20. I have a sense of humor.
21. I got through a difficult time with alcohol.
22. I’m not a religious fanatic (not that religion is bad).
23. I can keep a conversation going.
24. My sarcasm sometimes goes unnoticed.
25. I’m artistic.
26. I can solve a Rubik’s cube.
27. I can still take the derivative of an equation.
28. I look really good with a tan.
29. I don’t take shit from people.
30. For computers and the entire IT industry.
31. For movies and the entire movie industry (minus the MPAA — suck my balls)

Every computer science student at Hiram College is required to perform two research projects, called IRCs, prior to graduation.  Of the two projects I completed I am proudest of my Computer Vision project because it not only was one of the coolest things I’ve ever studied, but it also required an extensive amount of hard work to complete.  The satisfaction is still a source of motivation for me to this day.

The project’s in-depth details can be found at http://www.geigel.com/signlanguage/, however, briefly, I was able to employ computational methods, initially researched in the 1980s, to recognize American Sign Language letters within computer images.  (Note: The initial research performed in the 1980s focused on recognizing faces in images which have popularly become known as Eigenfaces).  The process is called Principal Component Analysis (PCA) and is widely considered to be a breakthrough discovery in the advancement of Computer Vision.  Much of PCA’s attractiveness comes from it’s ability to train similar, yet slightly different, images of a given class.  In my research, for instance, the classes I dealt with were signed letters corresponding to different hand orientations.  When it boils down to it, PCA is able to mathematically define (using Eigenvectors and Eigenvalues) the most important features of a given class (for example a fist for letter A versus the open cirlce for the letter O), and then when a new unknown image is presented to the system a calculation can be performed and a mathematically reinforced estimate can be made as to what class the unknown image belongs.

Ellen Walker, my Computer Vision professor at Hiram College, oversaw my research and offered help when I ran into issues.  Ultimately, I was able to develop/program/execute a fully functional PCA system in C++ for recognizing American Sign Language letters.  In fact, once the PCA system was trained, I was able to test it on 10 sample images with 100% recognition accuracy.  The project was a huge success!  Both in it’s results and in the lessons, knowledge, and gratification it left me.  Though Ellen has never explicitly said this to me, I think that she was also impressed and surprised with how well the results turned out.

This all took place in 2005 — the year I graduated from Hiram.  As the years went on I would occasionally correspond with Ellen and then on 11/29/2006 I received an email from her asking if my project could serve as a possible AI/Vision project that she would be submit to the University of Hartford’s “Machine Learning Experiences in AI” shared curriculum.  Of course I was excited and happy that my project would be the inspiration for such a project. 

A few years later I received another email from Ellen on 2/23/2009 saying that project was now appearing on Hartford’s website at http://uhaweb.hartford.edu/compsci/ccli/samplep.htm.  The project’s detail page can be found at this URL: http://uhaweb.hartford.edu/compsci/ccli/rasl.htm.  There’s also a PDF (http://cs.hiram.edu/~walkerel/RASLUPCA.pdf) that has in-depth details along with a credit at the very bottom stating that the project was inspired by my project!  In classic programmer speak — w00t!

It’s been nearly a year and a half in the making, but my friends and I finally got our Pi tattoos.  Chris Armenio, John Belter, Sean Teller and I went to Smokin’ Tattooz last night (11/29) in Kent and all got inked — some of us for the first time.  Noticeably wussing out and NOT getting a tattoo (even though she promised she would) was half-Asian Sarah Scroggy who nonetheless provided event planning services, and moral/emotional support.  

The tattoo appears slightly to the left of the center of my wrist, and along my watch band (so it can be hidden when it needs to be).  The entire tattoo fits within a 1 inch square.  The image on the bottom shows off 3.14 – 3 fingers up, wring finger down (point), pinky finger up for 1and the entire count of up fingers being 4.

Other important attendees during this historic event include: Mike Pavis, Lou Colorito, Katherine Dunn, Matt Coleman, Jeff Zimmerman, Caitin Ganley and Jeff Burk.  All of whom looked on as the rest of us endured.  Honestly, the needle wasn’t painful at all, and I was expecting much worse.

Why get Pi as a tattoo?  I can’t answer for anyone else, but for me I’ve wanted it for a long time.  There is beauty in mathematics, and Pi is an important number (ratio) used in calculations that define our world.  It’s infinite, never repeats itself, powerful in its simplicity and unique.  Pi is God’s number.

Additionally, the Greek letter Pi resembles neolithic Irish dolmens – or altars.  Dolmens pepper Ireland, and my dad and I saw a lot on our first visit there.  So in that way, my Pi tattoo will help remind me of those fun times.

Some of the dolmens my dad and I saw on our first Ireland trip.  Notice how similar dolmens are to the Greek letter Pi?
