BAI = Ball Annotation Interface

This directory contains a MATLAB GUI interface to annotate a ball marker
( e.g. on top of somebody's head) on a sequence of PPM files, as an ellipse.
The annotation is entered as the rectangular bounding box defining the ellipse.

This GUI includes a ball tracker to interpolate between manual measurements.

To use it, copy these three MATLAB files in a directory:

  head_annotation_interface.fig
  head_annotation_interface.m  ->  to launch from MATLAB 6.1
  do_balltrack.m

To see an example, copy the following two files in the same directory,
untar the first one, and lauch "head_annotation_interface" from MATLAB.

  seq6_iain2_cam1.tar.gz  ->   to untar 
  seq6_iain2_cam1_iain.headgt

For information about the format of the annotation file, see the file
called "FORMATS" in the parent directory.
