The present invention discloses a method of automatically detecting and tracking a face by an electronic capturing device that alternatively uses a face detecting algorithm to quickly locate a face in a frame based on a skin color model and a face tracking algorithm to locate a face in subsequent frames by a nonparametric technique and a mean shift algorithm. If the face tracking algorithm cannot track and locate a face correctly, the face detecting algorithm will be used again to detect a face position in another new frame until the face position is located successfully, and then the face tracking algorithm will be used again for detecting and locating the face position in subsequent frames. After this method has detected a face position, a variable focal lens is used to slowly and smoothly refocus the frame including a face region, so as to obtain a clear face image.

In various implementations, provided are techniques, as well as systems that implement these techniques, for SEI messages that distinguish “essential” information from “non-essential” information. In various implementations, an encoder can be configured to determine whether information associated with video data is essential or is not essential. In various implementations, different types of SEI messages can be defined, where one or more of these types of SEI messages can indicate whether information associated with a particular video is essential or not essential. Essential information is required for presenting the video data, and is not required for decoding the video data.
