摘要： Some embodiments include a video copy detection approach based on speeded up robust features (SURF) trajectory building, local sensitive hash (LSH) indexing, and spatial-temporal-scale registration. First, interesting points' trajectories are extracted by SURF. Next, an efficient voting based spatial-temporal-scale registration approach is applied to estimate the optimal transformation parameters (shift and scale) and achieve the final video copy detection results by propagations of video segments in both spatial-temporal and scale directions. To speed up the detection speed, local sensitive hash (LSH) indexing is used to index trajectories for fast queries of candidate trajectories.

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.
