Supervision-by-Registration: An Unsupervised Approach to Improve the Precision of Facial Landmark Detectors
Computer Vision and Pattern Recognition (CVPR)
In this paper, we present supervision-by-registration, an unsupervised approach to improve the precision of facial landmark detectors on both images and video. Our key observation is that the detections of the same landmark in adjacent frames should be coherent with registration, i.e., optical flow.
