BMP Image Sequences for Elliptical Head Tracking
The BMP image sequences used in the head tracking demos are available as a single file: headtracker_sequences.zip (64 MB). Alternatively, to download an individual sequence, click on one of the links below.
| BMP image sequence, as .zip file | Description |
|---|---|
 15.2 MB |
An extended sequence showing pan, tilt, and zoom control; occlusion; 360-degree rotation; and head tilting. |
 15.5 MB |
Another extended sequence similar to the previous one, also showing the overlapping of two faces. Notice the flesh-colored board in the background. |
 1.1 MB |
Simultaneous occlusion, rotation, and translation. |
 2.9 MB |
Severe occlusion of subject by another person. |
 1.5 MB |
An attempt to distract the tracker with elliptical hands. On the fourth try, the tracker was distracted. |
 4.1 MB |
Tilting, rotation, and zooming. |
 5.8 MB |
Three villains unsuccessfully trying to steal the ellipse. Notice the relatively large search range. |
 0.9 MB |
Jerky, back-and-forth head motion. Since the file plays in real time, it gives some indication of the tracker's actual speed. |
 1.5 MB |
The subject walking behind a cubicle. |
 0.9 MB |
Because the histogram model had little hair, the tracker failed when the subject rotated. |
 5.9 MB |
This time the villains were more successful. |
 2.9 MB |
More rotation and occlusion. |
 1.5 MB |
More rotation and distraction. |
 1.4 MB |
More rotation and distraction. |
 1.5 MB |
More rotation. |
 1.4 MB |
More rotation. |
Unfortunately, the original sequences without the ellipse overlaid were never saved, so the sequences above were obtained by removing the ellipse using a median filter. Some artifacts around the perimeter of the head are visible.
