This paper proposes a novel method for robust and auto-
matic realtime head tracking by fusing face and head cues
within a multi-state particle filter. Due to large appear-
ance variability of human head, most existing head tracking
methods use little object-specific prior knowledge, resulting
in limited discriminant power. In contrast, face is a distinct
pattern much easier to capture, which motivates us to in-
corporate a vector-boosted multi-view face detector[6] to
lend strong aid to general head observation cues including
