Labeling persons appearing in video frames with names detected
from the video transcript helps improving the video content
identification and search task. We develop a face naming
method that learns from labeled and unlabeled examples using
iterative label propagation in a graph of connected faces or
name-face pairs. The advantage of this method is that it can use
very few labeled data points and incorporate the unlabeled data
points during the learning process. Anchor detection and metric
learning for face classification techniques are incorporated into
the label propagation process to help boosting the face naming
performance. On BBC News videos, the label propagation
algorithm yields better results than a Support Vector Machine
classifier trained on the same labeled data.
