Real-time AdaBoost cascade face tracker based on likelihood map and optical flow. (arXiv:2210.13885v1 [cs.CV])

The authors present a novel face tracking approach where optical flow
information is incorporated into a modified version of the Viola Jones
detection algorithm. In the original algorithm, detection is static, as
information from previous frames is not considered. In addition, candidate
windows have to pass all stages of the classification cascade, otherwise they
are discarded as containing no face. In contrast, the proposed tracker
preserves information about the number of classification stages passed by each
window. Such information is …
