Dear all,
I have just downloaded imagej and I need some support.
I wish to use imagej to reconstruct the  trajectory of an animal whose motion  I have stored in a Avi format.
Is there any plug-in by which I can extract single frames and automatically store the x y positions of a reference point such as the head?
Thanks in advance
 

Luciana

In an ImageJ course i gave i listed several plugins which are capable to track motion data (automatically or not) which could be useful for your work:

Particle Tracking Plugins for ImageJ:

General links (ImageJ included!)

The *.avi can simply be imported in ImageJ. If necessary you have to decompress (or convert) the *.avi file.

Measurement can then be made frame by frame or maybee automatically with the aforementioned
plugins.

Best regards

Hi Luciana,

We track animal movement in avi movies using the MATLAB package DLTdv3
from the Ty Hedrick lab:
http://www.unc.edu/~thedrick/software1.html

It's OK but the interface and output format are a bit crusty (and you
need non-free MATLAB of course).

If you find that one of the ImageJ tracker plugins is good for
kinematics as well as bright particle tracking, please let us know!
