Digitally-Generated Lighting For Video Conferencing Applications

US Patent:
6980697, Dec 27, 2005
Filed:
Jan 25, 2002
Appl. No.:
10/057063
Inventors:
Andrea Basso - Ocean NJ, US
Eric Cosatto - Highlands NJ, US
David Crawford Gibbon - Lincroft NJ, US
Hans Peter Graf - Lincroft NJ, US
Shan Liu - Los Angeles CA, US
Assignee:
AT&T Corp. - New York NY
International Classification:
G06K009/40
US Classification:
382274, 382103, 382190, 382291, 348 1401
Abstract:
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.

Digitally-Generated Lighting For Video Conferencing Applications

US Patent:
7231099, Jun 12, 2007
Filed:
Aug 31, 2005
Appl. No.:
11/216997
Inventors:
Andrea Basso - Ocean NJ, US
Eric Cosatto - Highlands NJ, US
David Crawford Gibbon - Lincroft NJ, US
Hans Peter Graf - Lincroft NJ, US
Shan Liu - Los Angeles CA, US
Assignee:
AT&T - New York NY
International Classification:
G06K 9/40

US Classification:

Method For Video Transcoding With Adaptive Frame Rate Control

US Patent:
7330509, Feb 12, 2008
Filed:
Sep 12, 2003
Appl. No.:
10/661308
Inventors:
Ligang Lu - Somers NY, US
Shan Liu - Irvine CA, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04N 7/12
G06K 9/36
US Classification:
37524003, 382238
Abstract:
A video transcoding method is provided for transcoding a first signal stream compressed by a first coding scheme to a second signal stream compressed by a second coding scheme. The method employs an adaptive frame rate and a joint temporal-spatial rate control technique, such that the overall quality of compressed MPEG video can be significantly enhanced when the transcoding is controlled in the joint temporal (picture or frame rate) and spatial (quantization) domains. One embodiment considers transcoding from high bit rate video with larger image size (e. g. 4CIF/4SIF, CIF) coded by one coding technique, e. g. , MPEG-2 to a lower bit rate video with smaller image size (e. g. CIF, QCIF) coded by the same or another coding technique, e. g. , MPEG-4.

Method For Tracking The Disappearance Of Detected Logos Within Digital Video Signals

US Patent:
7356084, Apr 8, 2008
Filed:
Oct 9, 2003
Appl. No.:
10/682315
Inventors:
Shan Liu - Irvine CA, US
Assignee:
Samsung Electronics Co., Ltd. - Suwon
International Classification:
H04N 7/18
US Classification:
37524026
Abstract:
A method and system for sensing disappearance of the previously detected logos in noisy digital video signals. When a video program starts, a short period of time is allowed to initially detect the existence and the location of the logo within the incoming video frames. Once the logo is detected and a logo map is generated, logo tracking senses whether the logo remains in, or disappears from, the video frames. If the logo moves or (partially) changes its intensity, color, pattern, etc. , it will be sensed as having disappeared altogether.

Apparatus And Method For Detecting Opaque Logos Within Digital Video Signals

US Patent:
7483484, Jan 27, 2009
Filed:
Oct 9, 2003
Appl. No.:
10/682316
Inventors:
Shan Liu - Irvine CA, US
Assignee:
Samsung Electronics Co., Ltd. - Suwon
International Classification:
H04N 7/12
US Classification:
37524001, 375240, 37524012
Abstract:
A detection method and system that allows detecting an opaque logo after it has appeared in the digital video program for a short period of time, by deriving and analyzing the stochastic characteristics of the video signal along the temporal axis.
