Video-based Face Recognition
Three Challenge:
The quality of video is low. Usually, video acquisition occurs outdoors (or indoors but with bad conditions for video capture).
Face image are small: Make the recognition task more difficult, because affect the accuracy of face segmentation, as well as the accurate detection of the crucial points/landmarks that are often needed in recognition methods.
The characteristics of faces/human body parts: It is easier to localized a face, but not recognize an specific one.
