Still trying to get face tracking and Tracking working. I have point tracking working fine. I have tried to do this before and was told to put the haarcascade files somewhere. Can someone help me to get them to the right place, please. When I attempt face tracking the opencv shows the "haarcascade frontal" but it doesn't work. Sometimes the whole program shuts down.

Go in the libraries folder, mrlmainfolder/libraries/zip and unzip the haarcascade zipped folders into the main mrl folder (the One in the screenshoot)

unzipped the files and put them in .myrobotlab file. Still does not work. Sent a no worky

if you search for the word Traceback and find it in the log - it's usually a Python problem
This is what I found :

Traceback (most recent call last):
  File "<string>", line 58, in <module>

Ok, so the complaint is "pyramidDown" is not a method of Tracking ...
but on this line you are using it like one.

i01.headTracking.pyramidDown()

If you ever wonder what methods a Service has - you can use the techniques listed in this post to help you.

What you "might" want is to use the addFilter(String) method 

Here is it listed in the gui

What you probably want is :

i01.headTracking.addFilter("PyramidDown")

I've got the face tracking working now. Now I will work on getting it to move smoother - pretty jerky now - but hey it's working. Thanks for the help!
