The following demos are related to work presented in Workshop on Image Analysis

for Multimedia Interactive Services (WIAMIS `05).

 

 

From Section 4: Tracking Multiple People

 

These video sequences compare multi-object tracking for a standard particle filter (PF),

a particle filter using partitioned sampling (PS) sampling techniques, and a particle filter with
distributed partitioned sampling (DPS) sampling techniques.  The following video
files are video sequences from the 5 first runs of 50 tracking multiple object using
the above techniques.  The first five sequences track with a standard PF, the second
five track with PS, the third track with DPS.  Each sequence is separated by a blank
yellow frame. 

Real Sequence 1 - Three people are tracked through occlusion.  This sequence is used

to measure the trackers ability to recover from occlusion.

Real Sequence 2 - Three people are tracked through occlusion (for a longer duration than

in the first sequence).  This sequence is used to measure the trackers ability to recover

from occlusion.
 

From Section 5: Tracking Head Pose

 

These demos show the results of head tracking and pose estimation with a mixed-state PF

Each head is represented by a spatial configuration and a examplar-based head model.

of the image indicate the pan angle (1st clock) and the tilt angle (2nd clock).
