The goal of this project is to develop improved algorithms for face detection and segmentation from video imagery for use in facial recognition systems under current development by the government. Our approach consists of those major modules:
(1). Human detection and tracking via background modeling and particle filtering (2). Multi-view Face detection and tracking (3). Eye detection and tracking (4). Face recognition,
and performance modeling and prediction of face recognition
The goal of human motion detection is to identify motion candidate regions in the image possibly occupied by humans, assuming the motion in the scene is primarily caused by human movement. We are exploring different methods, such as background
modeling and optical flows estimation techniques. The particle filtering is applied to track person motion.
Given the identified image regions corresponding to the detected human, we then propose to use appearance-based face detection method. Two specific methods
are developed. We detect multi-view faces using discriminant features selected with AdaBoost.
The similar algorithm is also applied to
eye detection after face is located. Combined support
vector machine (SVM) is used to
detect the small face
(head) in cluttering environments.

Detected
faces are tracked through video. We combine multiple measurements
for
robust
multi-view
face tracking, and online learn face appearance models for individual
persons.
The
face
pose can be simultaneously estimated during tracking.
The face and eye detection and tracking provide good reference points for face
recognition.
A face recognition method based on local features is applied in the system.
Another
research on face recognition is to model and predict system
performance so that the
image
data that an existing face recognition system can not correctly
recognize will be
removed
from recognition.
Some results we have achieved so far are shown in this website.
