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!):
- FTIR_Cam: detects webcam and sends out frames to outlet.
- FTIR_VPlayer: reads quicktimes from path and sends out frames to outlet.
- 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.
Thanks,
Alain
I haven't looked at this yet, and have no external coding experience.
However, I'm wondering if it would be an easier task to port this library to mimic the pix_* objects in Gem? Maybe you could look at the Gem source and figure out how to do this. Or better yet, compare the code you have here with the pix_multiblob, and try to correct the algorithms as was suggested earlier.
Good luck!!!

Hi Alain,
wouldn't it be a lot easier to take the system that you already have and use OSC or FIDO to send the values (that you were printing) to PD for further processing?
I am greatly in favour of using different systems for different jobs
and letting
a protocol like OSC or fido (netsend) connect them together.
I could easily help you with that problem, if the code is running
already.
Cheers,
tim
