Filed:

Jun 9, 2011

Appl. No.:

13/156994

Inventors:

YU TIAN - Palo Alto CA, US
Peter Dean SWARTZ - San Jose CA, US

Assignee:

STMICROELECTRONICS INC. - COPPELL TX

International Classification:

H04N 7/32
G06K 9/48
H04N 5/225

US Classification:

34820711, 348699, 382197, 348E05062, 348E05024

Abstract:

Motion estimation systems and methods are disclosed. An apparatus may include a processing unit to acquire video images and to arrange the video images into a plurality of sequential video frames, and a motion estimation unit that receives the sequential video frames and determines a set of repetitive pattern neighbor candidate vectors for repetitive pattern content in a first frame. The set of repetitive pattern neighbor candidate vectors may be reduced by sorting the set to eliminate spurious repetitive pattern neighbor candidate vectors. The reduced set may be provided to a second adjacent frame. A method may include acquiring a plurality of sequential video frames having a repetitive pattern content, and determining a set of repetitive pattern neighbor candidate vectors for the repetitive pattern content in a first frame of the sequential video frames. The set of repetitive pattern neighbor candidate vectors may be sorted by determining at least one spurious repetitive pattern neighbor candidate vector. The sorted set may be provided to a second adjacent video frame.

Abstract:

An apparatus includes a data access circuit that interprets data records, each having a number of data fields, a record parsing circuit that determines a number of n-grams from terms of each of the data records and maps the number of n-grams to a corresponding number of mathematical vectors, and a record association circuit that determines whether a similarity value between a first mathematical vector for the first data record and a second mathematical vector for the second data record is greater than a threshold similarity value, and associates the first and second data records in response to the similarity value exceeding the threshold similarity value. An example apparatus includes a reporting circuit that provides a catalog entity identifier, associates each of the first term and the second term to the catalog entity identifier, and provides a summary of activity for an entity.
