View page
US Patent:
6963378, Nov 8, 2005
Filed:
Nov 1, 2002
Appl. No.:
10/286283
Inventors:
Zhu Li - Palatine IL, US
Bhavan Gandhi - Vernon Hills IL, US
Aggelos K. Katsaggelos - Chicago IL, US
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04N005/14
H04N009/64
US Classification:
348700
Abstract:
At least one visual significance metric is determined () for at least some frames belonging to an original series of frames (). Key frames are identified () as a function, at least in part, of the visual significance metric. Cumulative visual significance values are then determined () for at least some of the frames that intervene between each pair of key frames. These cumulative visual significance values are then used to identify () frames of additional content interest. Various frames are then selected () for use in a visual summary. In one embodiment, all of the key frames and frames of additional content interest are selected for inclusion in the visual summary.

Method For Fuzzy Logic Rule Based Multimedia Information Retrival With Text And Perceptual Features

View page
US Patent:
7065521, Jun 20, 2006
Filed:
Mar 7, 2003
Appl. No.:
10/383897
Inventors:
Zhu Li - Palatine IL, US
Bhavan Gandhi - Vernon Hills IL, US
Brett L. Lindsley - Wheaton IL, US
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
G06F 17/30
US Classification:
707 3, 707 4
Abstract:
A search system () for a database () including records having a multiple disparate types of media is provided. The search system supports queries, that include different types of search criteria, including content based retrieval search criteria. A fuzzy logic method () is provided for effectively combining the results of different types of search criteria. The fuzzy logic method also allows confidence levels entered by the user for search criteria to be considered in combining results. Retrieval relevance values for documents for at least some search criteria are used in the fuzzy logic method. For content based image retrieval searches, the retrieval relevance values are computed by mapping a distance between quantitative characterizations of a search basis image, and other images into a finite range.

In-Picture Prediction For Video Coding

View page
US Patent:
8379995, Feb 19, 2013
Filed:
May 15, 2008
Appl. No.:
12/121316
Inventors:
Anthony R. May - Winchester, GB
Shih-Ta Hsiang - Schaumburg IL, US
Faisal Ishtiaq - Chicago IL, US
Zhu Li - Palatine IL, US
Assignee:
Motorola Mobility LLC - Libertyville IL
International Classification:
G06K 9/36
G06K 9/46
US Classification:
382238, 382243
Abstract:
A method of coding video content. The method can include, identifying a first plurality of image blocks within a picture based on at least a first image characteristic that is common to each of the first plurality of image blocks. A first image block group can be dynamically defined. At least one of the image blocks can be selected as a predictor block to predict other image blocks within the first image block group. In another arrangement, at least a first image block and a second image block can be identified within a picture. The second image block can be predicted from the first image block. A displacement vector can be defined to associate the second image block with the first image block. A value representing the displacement vector can be included within a header of the second image block.

Method And Apparatus For Characterizing A Video Segment And Determining If A First Video Segment Matches A Second Video Segment

View page
US Patent:
20050125821, Jun 9, 2005
Filed:
Nov 17, 2004
Appl. No.:
10/990583
Inventors:
Zhu Li - Palatine IL, US
Bhavan Gandhi - Vernon Hills IL, US
Aggelos Katsaggelos - Chicago IL, US
International Classification:
H04B001/66
H04N007/16
H04N011/04
H04N011/02
US Classification:
725019000, 375240270, 382181000, 382173000
Abstract:
A method and apparatus for determining if a first video segment matches a second video segment is provided herein. Each video segment to be compared has an associated metric (H), which is a function over time as the conditional entropy between frame fand previous frame f. A comparison of each video segment's Hvectors determines if the video segments match.

Video Encoding System And Method For Providing Content Adaptive Rate Control

View page
US Patent:
20070036227, Feb 15, 2007
Filed:
Aug 15, 2005
Appl. No.:
11/204212
Inventors:
Faisal Ishtiaq - Chicago IL, US
Bhavan Gandhi - Vernon Hills IL, US
Zhu Li - Palatine IL, US
International Classification:
H04N 7/12
US Classification:
375240260
Abstract:
A video encoding system () provides content adaptive rate control that includes a visual analyzer () utilizing at least one visual analysis tool for processing a video frame to provide visual information describing the video frame. An encoder () generates encoding status information relating to the video frame being processed. A rate controller () is responsive to the encoding status information generated by the encoder () and the visual information generated by the visual analyzer () to generate a rate control adjustment signal. The encoder () is responsive to the rate control adjustment signal for encoding the video frame.

Method And System For Intelligent Video Adaptation

US Patent:
20080123741, May 29, 2008
Filed:
May 3, 2007
Appl. No.:
11/744100
Inventors:
ZHU LI - PALATINE IL, US
FAISAL ISHTIAQ - CHICAGO IL, US
Assignee:
MOTOROLA, INC. - SCHAUMBURG IL
International Classification:
H04N 7/12
H04B 1/66
US Classification:
37524012, 37524001, 37524003, 375E07092
Abstract:
A system () and method () for efficient video adaptation of an input video () is provided. The method can include segmenting () the input video into a plurality of video shots () using a video trace () to exploit a temporal structure of the input video, selecting () a subset of frames () for the video shots that minimizes a distortion of adapted video () using the video trace, and selecting transcoding parameters () for the subset of frames to produce an optimal video quality of the adapted video under constraints of frame rate, bit rate, and viewing time constraint. The video trace is a compact representation for temporal and spatial distortions for frames in the input video. A spatio-temporal rate-distortion model () provides selection of the transcoding parameters during adaptation.

US Patent:
20090323575, Dec 31, 2009
Filed:
Jun 27, 2008
Appl. No.:
12/147809
Inventors:
Zhu Li - Palatine IL, US
Ethan Y. Chen - Wilmette IL, US
Faisal Ishtiaq - Chicago IL, US
Hua Xu - Lake Zurich IL, US
John M. Harris - Glenview IL, US
Assignee:
MOTOROLA, INC. - Schaumburg IL
International Classification:
H04H 20/71
US Classification:
370312
Abstract:
A number of uplink transmissions from multiple remote devices is received. The remote devices correspond to a single network node, and each of the uplink transmissions corresponds to a request for content. A subset of remote devices whose uplink transmissions correspond to requests for common content is identified and a Quality of Service (QoS) level corresponding to the number of remote devices in the identified subset is determined. The common content is transmitted to the single network node at the determined QoS level.
