intersection. Work is also progressing on 3D visualization of the intersection. The latest
development version of TDAA can be obtained using Subversion software
(http://www.sourceforge.net/subversion) from our Subversion server
(svn://hcvl.hci.iastate.edu/DOT/TDAA).
The remainder of this section walks through the graphical dialog boxes associated with the video
capture and image extraction process, the image processing process, and data visualization
process. Upon startup of TDAA, a master dialog box appears allowing the user to select which of
these three activities the user would like to begin (See Figure 6.1).

6.1 Video Capture and Image Extraction
The primary dialog box for the video capture and image extraction process is shown in Figure
6.2. In TDAA, all data relevant to a given analysis are stored within a Project file. The default
Project file is called ‘default.tdaa.’ All Project files are required to have the ‘.tdaa’file extension.
The first step in the video capture process is to choose an existing project file or to create a new
project file by clicking the Choose or New buttons in the Capture Options Panel.
