摘要： Dense range data obtained at real-time rates is employed to estimate the pose of an articulated figure. In one approach, the range data is used in combination with a model of connected patches. Each patch is the planar convex hull of two circles, and a recursive procedure is carried out to determine an estimate of pose which most closely correlates to the range data. In another aspect of the invention, the dense range data is used in conjunction with image intensity information to improve pose tracking performance. The range information is used to determine the shape of an object, rather than assume a generic model or estimate structure from motion. In this aspect of the invention, a depth constraint equation, which is a counterpart to the classic brightness change constraint equation, is employed. Both constraints are used to jointly solve for motion estimates.

摘要： An electronic system for integrating a user's moving image into a computer-generated pictorial environment, and allowing the user to interact with the environment and objects therein. The environment is rendered on a screen display in a manner that simulates three dimensions, including respect for occlusion relationships among the user and objects in the environment. The resulting image, which changes as the user gestures and interacts with the environment, is projected onto a large screen that the user faces. The environment includes a series of mobile entities, or "agents," which respond to one or more of the user's changing position, gestures and voice, exhibiting context-dependent behavior that appears semi-intelligent.

摘要： A mobile deixis device includes a camera to capture an image and a wireless handheld device, coupled to the camera and to a wireless network, to communicate the image with existing databases to find similar images. The mobile deixis device further includes a processor, coupled to the device, to process found database records related to similar images and a display to view found database records that include web pages including images. With such an arrangement, users can specify a location of interest by simply pointing a camera-equipped cellular phone at the object of interest and by searching an image database or relevant web resources, users can quickly identify good matches from several close ones to find an object of interest.
