in the future one of my projects is shape recognition.  I have been 
wanting to play with it for a while now.

bari on irc mentioned
https://github.com/firepick1/FireSight/wiki/firesight
which is based on opencv.  I installed it and it seems to work as 
expected.  you can use a command line to test pipelines.  It uses a c++ 
library and json for communication.  It is mainly used for pick and 
place machines.

I wanted to play with python and found that opencv natively has a python 
wrapper.. (I may not be using the terms correctly)

so I created a small program (mainly a copy and paste from some examples)

it takes video from input 0 (my web cam)  looks for circles that are 
between 10 and 15 pixels radius and draws a bulls eye.

this is my first real exposure to python. the next step is to see how I 
can fidldle hal stuff with it..

This seems like it would have some real applications.  There are 
different detectors - circles are just one of many..
