US Patent:

Filed:

Oct 26, 2006

Appl. No.:

11/553382

Inventors:

Ming-Hsuan Yang - Sunnyvale CA, US
Rui Li - Boston MA, US

Assignee:

Honda Motor Co., Ltd. - Tokyo

International Classification:

G06K 9/00

US Classification:

382103, 382285, 345474

Abstract:

Disclosed is a method and system for efficiently and accurately tracking three-dimensional (3D) human motion from a two-dimensional (2D) video sequence, even when self-occlusion, motion blur and large limb movements occur. In an offline learning stage, 3D motion capture data is acquired and a prediction model is generated based on the learned motions. A mixture of factor analyzers acts as local dimensionality reducers. Clusters of factor analyzers formed within a globally coordinated low-dimensional space makes it possible to perform multiple hypothesis tracking based on the distribution modes. In the online tracking stage, 3D tracking is performed without requiring any special equipment, clothing, or markers. Instead, motion is tracked in the dimensionality reduced state based on a monocular video sequence.

US Patent:

7720977, May 18, 2010

Filed:

Feb 11, 2003

Appl. No.:

10/364892

Inventors:

Rui Li - Alviso CA, US

Assignee:

Foundry Networks, Inc. - Santa Clara CA

International Classification:

G06F 15/16

US Classification:

709228, 709223, 709227, 709230, 709238

Abstract:

A switch may be used to force the expiration of a cookie on a user's system by inserting an expiration field into the cookie contained in a network response packet. Additionally, a mechanism is provided to delete or damage a cookie contained in a network request packet, so that server software is not disrupted by the receipt of a cookie. Deleting a cookie results in a cleaner request, but damaging a cookie may be more efficient in certain circumstances. By providing these features, an efficient cookie switching design is provided.

US Patent:

20230083621, Mar 16, 2023

Filed:

Jul 22, 2022

Appl. No.:

17/871341

Inventors:

- San Ramon CA, US
Hsin-wei Tsao - Menlo Park CA, US
Rui Li - Menlo Park CA, US

International Classification:

G06Q 30/02
G06F 16/2457
G06F 16/9536
G06N 20/00

Abstract:

Entity scoring calibration includes receiving values for a metric by which to calibrate a reputation scoring model. The reputation scoring model is usable to determine a reputation score. The reputation scoring model to be calibrated is based at least in part on a set of model parameters associated with reputation scoring components. It further includes receiving a plurality of feedback items pertaining to one or more entities. It further includes calibrating the reputation scoring model at least in part by adjusting at least some of the model parameters associated with the reputation scoring components such that reputation scores generated by the calibrated reputation scoring model track the values for the metric.

A63F 13/79
A63F 13/85

Abstract:

Techniques for improving a user video game experience are described. In an example, a computer system accesses videos showing separate completions of an activity by a plurality of video game players. From a definition of the activity, it is determined that the activity is a parent of sub-activities. Links to video portions of the videos are generated, wherein each video portion corresponds to a sub-activity. A score is generated for each video portion based on a relevance of each video portion to a user. The links are presented in a user interface to the user based on the score for each video portion, wherein upon selection of a first link, the user interface displays a first video to the user starting at a first video portion showing a completion of a sub-activity by a video game player.
