US Patent:

8498487, Jul 30, 2013
Filed:

Oct 31, 2008
Appl. No.:

12/262463
Inventors:

Gajinder Singh - Noida, IN
Manika Puri - Princeton NJ, US
Jeffrey Lubin - Princeton NJ, US
Harpreet Singh Sawhney - Princeton NJ, US
Assignee:

SRI International - Menlo Park CA
International Classification:

G06K 9/50
US Classification:

382201, 382124, 707999006
Abstract:

A computer implemented method computer implemented method for deriving a fingerprint from video data is disclosed, comprising the steps of receiving a plurality of frames from the video data; selecting at least one key frame from the plurality of frames, the at least one key frame being selected from two consecutive frames of the plurality of frames that exhibiting a maximal cumulative difference in at least one spatial feature of the two consecutive frames; detecting at least one 3D spatio-temporal feature within the at least one key frame; and encoding a spatio-temporal fingerprint based on mean luminance of the at least one 3D spatio-temporal feature. The least one spatial feature can be intensity. The at least one 3D spatio-temporal feature can be at least one Maximally Stable Volume (MSV). Also disclosed is a method for matching video data to a database containing a plurality of video fingerprints of the type described above, comprising the steps of calculating at least one fingerprint representing at least one query frame from the video data; indexing into the database using the at least one calculated fingerprint to find a set of candidate fingerprints; applying a score to each of the candidate fingerprints; selecting a subset of candidate fingerprints as proposed frames by rank ordering the candidate fingerprints; and attempting to match at least one fingerprint of at least one proposed frame based on a comparison of gradient-based descriptors associated with the at least one query frame and the at least one proposed frame.

US Patent:

8619144, Dec 31, 2013
Filed:

Mar 14, 2012
Appl. No.:

13/419857
Inventors:

Samuel Henry Chang - San Jose CA, US
Manika Puri - Santa Clara CA, US
Edward Dietz Crump - Santa Cruz CA, US
Steve G. Gonzalez - Davenport CA, US
Assignee:

Rawles LLC - Wilmington DE
International Classification:

H04N 17/00
US Classification:

348187, 348180
Abstract:

Devices and techniques are described for automatically calibrating a camera system. The camera system undergoing calibration is coupled to a computing device and an automated positioning platform coupled to a target structure. The computing device acquires images from the camera of the target structure in a plurality of repeatable poses. From these acquired images, intrinsic camera parameters may be determined. Once determined, the parameters may be used to correct images acquired by the camera system.

US Patent:

20100173269, Jul 8, 2010
Filed:

Jan 6, 2010
Appl. No.:

12/683124
Inventors:

Manika Puri - Fremont CA, US
Zhiwei Zhu - Plainsboro NJ, US
Jeffrey Lubin - Princeton NJ, US
Tom Pschar - Ringoes NJ, US
Ajay Divakaran - Monmouth Junction NJ, US
Harpreet S. Sawhney - West Windsor NJ, US
International Classification:

G09B 19/00
US Classification:

434127
Abstract:

A method and system for analyzing at least one food item on a food plate is disclosed. A plurality of images of the food plate is received by an image capturing device. A description of the at least one food item on the food plate is received by a recognition device. The description is at least one of a voice description and a text description. At least one processor extracts a list of food items from the description; classifies and segments the at least one food item from the list using color and texture features derived from the plurality of images; and estimates the volume of the classified and segmented at least one food item. The processor is also configured to estimate the caloric content of the at least one food item.
