Python + Motion detection = Fweemote

jedie writes "After reading about different Wiimote hacks on Slashdot I decided to make a video with some demos of my motion-detection library. You can watch the video here. There's a link to the sourcecode (GPL) as well, but the demo is win32 only. It's basically a webcam and some software in python to track LEDs (preferrably IRs). In the demo video, you see the software (albeit badly because of the webcam's IR filter being removed) tracking two differently colored LEDs, so multiplayer is possible. The software can track multiple points easily, and when combined with IR-LEDs, it's easy to simulate one Wiimote (i.e. calculating the distance and angle between two IR-LEDs to determine where the remote is relative to the webcam). I want the code to get some publicity, because I don't have time to work on it (dissertation, blabla) but I don't want the code (however messy it is) to go to waste."

I hear that. Anyone with any real knowledge knows that these days language is mostly a matter of preference. Of course, Python is my language of choice and I do love how beautiful the code looks no matter how convoluted you try and write it.

raw = os.popen('dir /B').read().rstrip().split('\n')

To be perfectly honest, however, I use certain languages for different things. Rather, I use Perl for IM stuff (AIM, IRC, etc), PHP on my sites, and Python for those two plus everything else including a teaching tool.

What's wrong with the Python interface to Intel's immensely popular OpenCV. Firewire devices, USB, multiple cameras.. all are a breeze on Linux or those-other-two-popular-OS's.

Using a Debian-based system as example:

apt-get install python-opencv

In a Python interpreter do:

from opencv import cv

then:

help(cv)

.. and prosper.

Apparently, it's not very good at letting me know it exists =P. Thanks, I'll give it a whirl.

You can't write 'because' either.

"I do love how beautiful the code looks no matter how convoluted you try and write it."

if code aesthetics are really important to you, they you really must go with basic.

10 CLS
20 PRINT "Hello world"
30 END

Look at the beautiful symmetry!
Look at the even row of numbers in one column, and how they prop up the commands sitting beside them.

I must say, BASIC code is truly an example of sublime beauty.
I pity the fool who codes in Python.
