摘要： A video communication system that replaces actual live images of the participating users with animated avatars. A method may include initiating communication between a first user device and a remote user device; receiving selection of a new avatar to represent a user of the first user device; identifying a new avatar file for the new avatar in an avatar database associated with the first user device; determining that the new avatar file is not present in a remote avatar database associated with the remote user device; and transmitting the new avatar file to the remote avatar database in response to determining that the new avatar file is not present in the remote avatar database.

摘要： Avatars are animated using predetermined avatar images that are selected based on facial features of a user extracted from video of the user. A user's facial features are tracked in a live video, facial feature parameters are determined from the tracked features, and avatar images are selected based on the facial feature parameters. The selected images are then displayed are sent to another device for display. Selecting and displaying different avatar images as a user's facial movements change animates the avatar. An avatar image can be selected from a series of avatar images representing a particular facial movement, such as blinking. An avatar image can also be generated from multiple avatar feature images selected from multiple avatar feature image series associated with different regions of a user's face (eyes, mouth, nose, eyebrows), which allows different regions of the avatar to be animated independently.
