摘要： A cost-effective and computationally efficient hand gesture recognition system for detecting and/or tracking a face region and/or a hand region in a series of images. A skin segmentation model is updated with skin pixel information from the face and iteratively applied to the pixels in the hand region, to more accurately identify the pixels in the hand region given current lighting conditions around the image. Shape features are then extracted from the image, and based on the shape features, a hand gesture is identified in the image. The identified hand gesture may be used to generate a command signal to control the operation of an application or system.

摘要： A video communication system that replaces actual live images of the participating users with animated avatars. The system allows generation, rendering and animation of a two-dimensional (2-D) avatar of a user's face. The 2-D avatar represents a user's basic face shape and key facial characteristics, including, but not limited to, position and shape of the eyes, nose, mouth, and face contour. The system further allows adaptive rendering for displaying allow different scales of the 2-D avatar to be displayed on associated different sized displays of user devices.

摘要： In response to a gestural command, a video currently being watched can be identified by extracting at least one decoded frame from a television transmission. The frame can be transmitted to a separate mobile device for requesting an image search and for receiving the search results. The search results can be used to obtain more information. The user's social networking friends can also be contacted to obtain more information about the clip.

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.
