This release is for the SGI IRIX 6.5 platform. The file you download is called headtracker.tar.gz. After you download it, type at the UNIX shell
gunzip headtracker.tar.gz tar xf headtracker.tarThat will create a directory called headtracker, with the following contents:
For example, after you untar the file and you go to the headtracker directory, to run the program you can type
glmain movies/jal8.rawA window should immediately pop up, and after some initialization you should be able to see the head being tracked in the sequence. As long as the program is running, the program window should not be covered by any other windows on the screen.
NOTE: Reading a movie file from the disk is currently the bottleneck in our system. Using our O2's we can achieve a frame rate of about 2 frames per second when we have to read the movie from a file. Using live input from a camera, we can achieve rates of up to 15 frames per second.
For a detailed description of the head tracking algorithms, please look at the following on-line publications.
