For the last 2 weeks I have been trying to write a motion tracking external using the blob motion 
tracker in opencv.  I had success with writing a program that recieves a path to an avi and motion 
tracks the blobs and prints their position.  Now I am writing the set of Pd externals using the same 
code with very little success. I need someone that knows what they are doing to look at my Pd code 
and show me what I am doing wrong.  I have read and followed IOhannes guide on external writing.  
Also, I have looked at the zexy and pdp sorce code in order to learn but still I am not getting it to work.  
The externals are based on the already working code I was able to frankenstein together.  I am 
calling it FTIR_Tools.  It consist of the following (if I ever get them to work!):

1. FTIR_Cam: detects webcam and sends out frames to outlet.
2. FTIR_VPlayer: reads quicktimes from path and sends out frames to outlet.
3. FTIR_Tracker: tracks blobs, sends out "matrix blob# position" to outlet2 and frames to outlet 1.
you can also turn on and off visuals for center point and bounding box.
4. FTIR_Window: displays frames in an X11 window.

Please look at my code and show me how to fix it. I am getting nowhere.  In the cvBloblib.zip is the 
program I put together called Tracker and the code called Tracker.cpp.  If you want to see how it 
works drag it to terminal and follow it with a path to an .avi. You must have opencv and fink installed.  
If you have ploblems installing opencv post and I will be glad to help.
