3D Motion Data
To represent 3D motion data, 3D human body model is required. Our 3D human body model
consists of 21 segments, which is shown in Figure 1. 3D motion data is saved in
Motion Analysis’s HTR (Hierarchical Translation Rotation) format, which contains the hierarchy of 3D human body
model, the base position of each segment and 3D translation and rotation
difference between adjacent frames at each segment.

The
storage required per subject is approximately 20MB. Thus, the total storage
requirement for 20 subjects is about 400MB. Figure 2 shows 3D motion data of ‘Bending a waist’ gesture (sample).

2D Stereo-Video Data
2D Stereo video data are captured by 3pair. We captured 24 gestures from 3 sets of stereo cameras at different directions.
Thus, 6 sets of 320 x 240 color video data from stereo cameras are generated
for each gesture. The storage required per subject for uncompressed ‘AVI' files
is approximately 4.5GB. The total storage requirement for 2D stereo-video data
of 20 subjects is about 90GB. Figure 3 shows the example of 2D stereo-video
data for ‘Bending a waist’ gesture (sample).

2D Silhouette Data
When the 2D
stereo-video data is captured, more than 500 frames of background video data
without any subject are saved for each subject. For instance, to separate subjects who
perform ‘sitting on a chair’ and ‘standing up from a
chair’ gestures, the background video data with only a chair and without
a subject is also captured. The 2D stereo-video data and the background video
data are converted to 8 bit gray-level images. We synthesize 2D silhouette
data, in which the region of background is ‘0’ and the region of a
subject is ‘1’ using the background video data, and save them as
binary BMP format. Figure 4 shows the example of 2D silhouette data for
‘Bending a waist’ gesture (sample).
