Patent number: 8955031Abstract: The invention provides a system and method that transforms a set of still/motion media (i.e., a series of related or unrelated still frames, web-pages rendered as images, or video clips) or other multimedia, into a video stream that is suitable for delivery over a display medium, such as TV, cable TV, computer displays, wireless display devices, etc. The video data stream may be presented and displayed in real time or stored and later presented through a set-top box, for example. Because these media are transformed into coded video streams (e.g. MPEG-2, MPEG-4, etc.), a user can watch them on a display screen without the need to connect to the Internet through a service provider. The user may request and interact with the desired media through a simple telephone interface, for example. Moreover, several wireless and cable-based services can be developed on the top of this system.Type: GrantFiled: August 8, 2011Date of Patent: February 10, 2015Assignee: AT&T Intellectual Property II, L.P.Inventors: Andrea Basso, Eric Cosatto, Steven Lloyd Greenspan, David M.

Patent number: 8638846Abstract: Systems and methods for encoding/decoding a video stream. Animated talking heads are coded using partial offline encoding, multiple video streams, and multiple reference frames. The content of a face animation video that is known beforehand is encoded offline and the remaining content is encoded online and included in the video stream. To reduce bit rate, a server can stream multiple video sequences to the client and the video sequences are stored in the client's frame store. The server sends instructions to play a particular video sequence instead of streaming the particular video sequence. Multiple video streams can also be streamed to the client. Positional data and blending data are also sent to properly position one video stream relative to another video stream and to blend one video stream into another video stream.Type: GrantFiled: June 23, 2003Date of Patent: January 28, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Eric Cosatto, Hans Peter Graf, Joern Ostermann

Publication number: 20140023237Abstract: A method of improving the lighting conditions of a real scene or video sequence. Digitally generated light is added to a scene for video conferencing over telecommunication networks. A virtual illumination equation takes into account light attenuation, lambertian and specular reflection. An image of an object is captured, a virtual light source illuminates the object within the image. In addition, the object can be the head of the user. The position of the head of the user is dynamically tracked so that an three-dimensional model is generated which is representative of the head of the user. Synthetic light is applied to a position on the model to form an illuminated model.Type: ApplicationFiled: September 24, 2013Publication date: January 23, 2014Applicant: AT&T Intellectual Property II, L.P.Inventors: Andrea Basso, Eric Cosatto, David Crawford Gibbon, Hans Peter Graf, Shan Liu

Patent number: 8135202Abstract: An automated method and system for analyzing a digital image of a biopsy to determine whether the biopsy is normal or abnormal, i.e., exhibits some type of disease such as, but not limited to, cancer. In the method and system, a classifier is trained to recognize well formed nuclei outlines from imperfect nuclei outlines in digital biopsy images. The trained classifier may then be used to filter nuclei outlines from one or more digital biopsy images to be analyzed, to obtain the well formed nuclei outlines. The well formed nuclei outlines may then be used to obtain statistics on the size or area of the nuclei for use in determining whether the biopsy is normal or abnormal.Type: GrantFiled: June 2, 2008Date of Patent: March 13, 2012Assignee: NEC Laboratories America, Inc.Inventors: Eric Cosatto, Hans-Peter Graf, Matthew L.
