摘要： The convex hull of two polygons having congruent corresponding angles with the same orientation can be determined by analyzing the relationship of each vertex of one of the polygons relative to its adjacent vertices. More particularly a line may be defined between a selected vertex on one of the polygons and its corresponding vertex on the other polygon. If the vertices adjacent to the selected vertex both fall on the same side of the line, then a line connecting the selected vertex with its corresponding vertex lies on the convex hull of the two polygons. If, on the other hand, the vertices adjacent to the selected vertex are located on different sides of the line, then the line connecting the selected vertex with its corresponding vertex does not lie on the convex hull.

摘要： A system and method for facilitating low bandwidth video image transmission in video conferencing systems. A target is acquired (video image of a person's head) and processed to identify one or more sub-regions (e.g., background, eyes, mouth and head). The invention incorporates a fast feature matching methodology to match a current sub-region with previously stored sub-regions. If a match is found, an instruction is sent to the receiving computer to generate the next frame of video data from the previously stored blocks utilizing a texture synthesis technique. The invention is applicable for video conferencing in low bandwidth environments.

摘要： A system and method that includes a virtual human face generation technique which synthesizes images of a human face at a variety of poses. This is preferably accomplished using just a frontal and profile image of a specific subject. An automatic deformation technique is used to align the features of a generic 3-D graphic face model with the corresponding features of these pre-provided images of the subject. Specifically, a generic frontal face model is aligned with the frontal image and a generic profile face model is aligned with the profile image. The deformation procedure results in a single 3-D face model of the specific human face. It precisely reflects the geometric features of the specific subject. After that, subdivision spline surface construction and multi-direction texture mapping techniques are used to smooth the model and endow photometric detail to the specific 3-D geometric face model. This smoothed and texturized specific 3-D face model is then used to generate 2-D images of the subject at a variety of face poses. These synthesized face images can be used to build a set of training images that may be used to train a recognition classifier.

摘要： A system and method for providing a peer-to-peer photo-sharing environment. The system includes: manual and automatic photo annotation at the client; periodic client-server synchronization; an index of client photos on a central server or a photo database that is resident on the central server, which is updated by the client-server synchronization function; end-user search functionality to search the centralized index or photo database; and transmission of the relevant photos to the client via an on-line image cache. In one embodiment, one client's new photos are automatically displayed on another client's computer (e.g., via screen saver or another mechanism).

摘要： A system and method for real-time multi-view (i.e. not just frontal view) face detection. The system and method uses a sequence of detectors of increasing complexity and face/non-face discriminating thresholds to quickly discard non-faces at the earliest stage possible, thus saving much computation compared to prior art systems. The detector-pyramid architecture for multi-view face detection uses a coarse-to-fine and simple-to-complex scheme. This architecture solves the problem of lengthy processing that precludes real-time face detection effectively and efficiently by discarding most of non-face sub-windows using the simplest possible features at the earliest possible stage. This leads to the first real-time multi-view face detection system which has the accuracy almost as good as the state-of-the-art system yet 270 times faster, allowing real-time performance.

摘要： A novel statistical learning procedure that can be applied to many machine-learning applications is presented. Although this boosting learning procedure is described with respect to its applicability to face detection, it can be applied to speech recognition, text classification, image retrieval, document routing, online learning and medical diagnosis classification problems.

摘要： A touch-sensitive device for use as an electronic input device for controlling by scrolling the visible portion of a document or image relative to a display. The device can include various improved configurations such as physically separate opposed input surfaces at opposite longitudinal ends and/or lateral sides. The end regions of a touch sensitive surface may be rounded and/or tapered to provide relative positional feedback to the user. Tactile positional feedback can also include surface texture changes on the scrolling area and/or changes in the surface of the frame in the region immediately adjacent the scrolling area. The touch sensitive areas may be provided within a split alphanumeric section of an ergonomic keyboard to enable scrolling without the user having to remove his or her hands from the alphanumeric section.
