Source: this database is
constructed by our own research group in a project funded by Honda and AFOSAR.
Purpose: this database is used to develop
non-invasive techniques for monitoring human fatigue.
It consists of three subsets:
o
Fatigue image sequences
·
This subset contains the
fatigued people sequences. It is used to study how the visual cues (e.g., eye
blinking, eyebrow movements, head movements, and yawning) relate to human
fatigue
·
5 subjects
·
5 image sequences
·
without groundtruth
o
Face images
·
This subset contains video
images of human subjects during the fatigue study
·
9 subjects
·
22 image sequences
·
with groundtruth of subject
identification and the detection results of the three face pose angles (pan,
tilt and roll) for the corresponding frames
o
IR Eye images
·
This subset contains IR eye
images of the human subjects during the fatigue study
·
9 subjects
·
22 image sequences
·
with groundtruth of subject
identification and the detection results of eye parameters for the
corresponding frames:
- ratio of the pupil ellipse width vs. height
- ratio of the detected pupil size and the fitted ellipse
size
- pupil size
- x, y coordinates of pupil center in the image
- x, y coordinates of pupil-glint vector
- the mapping region of the gaze (the screen is divided
into several regions)
- the persac parameter
- status of the eye: open, closed, and no eye
- the perclos parameter
- aecs parameter
