Aug 10, 2011

Appl. No.:

13/206856

Inventors:

John R. Zhang - Calgary, CA
Yansong Ren - Plano TX, US
Fangzhe Chang - Edison NJ, US
Thomas L. Wood - Colts Neck NJ, US

Assignee:

Alcatel Lucent - Paris

International Classification:

G06K 9/68
G06K 9/46

US Classification:

382218, 382201

Abstract:

A method for comparing videos includes detecting local features in frames of a video and determining the positions of detected local features in a first frame compared to their respective positions in a succeeding second frame. For at least some of the detected local features, a movement indicator is generated representing the position of a local feature in the first frame relative to the position of that local feature in the second frame, the movement indicator including an orientation, to obtain a plurality of movement indicators. Movement indicators are grouped by orientation ranges. The number of grouped movement indicators in an orientation range are summed to obtain a value for that orientation range. A time series of values for at least one given orientation range is obtained by determining the positions of detected local features in a first frame compared to their respective positions in a succeeding second frame for a plurality of pairs of frames. For at least one orientation range, a first time series of values for a first video is compared with a second time series of values for a second video to determine the similarity of the first and second videos.

International Classification:

G06K 9/68

US Classification:

382218, 707769, 707E17014

Abstract:

Video files stored in a data store are managed by analyzing the semantic relationship of at least one associated descriptive tag of a given video file to tags associated with video files in the data store. The results of the analysis are used to select a set of video files from those stored in the data store. The content of the given video file is compared with the content of the selected set to determine the similarity of the content. The results of the determination may be used to update information concerning the similarity of video files in the data store, for example, to be used in providing results in response to a search query.

International Classification:

G06K 9/68

US Classification:

382218

Abstract:

In a method of comparing a query video and a target video, frames of the query video and frames of the target video arc partitioned into blocks. The mean intensity value is calculated for each block. Minima and maxima values are extracted from temporal changes of the mean intensity values for each block. Inclines and declines are obtained from the minima and maxima values. The inclines and declines are used in determining if alignment exists between the query video and the target video.

International Classification:

US Classification:

382218

Abstract:

A method for comparing a query video and a target video includes partitioning frames of the query video and frames of the target video into blocks and calculating the mean intensity value for each block. A plurality of query time series is produced for the query video, each query time series representing temporal variation in mean intensity value for blocks from the same location in different frames of the query video. A plurality of target time series is produced for the target video, each target time series representing temporal variation in mean intensity value for blocks from the same location in different frames of the target video the query time series and the target time series are used in determining if alignment exists between the query video and the target video.

International Classification:

H04L 9/00

US Classification:

380200

Abstract:

A method for authenticating video content includes: receiving a digital signature, an unsecured video fingerprint, and an unsecured video content from a transmitting node at a receiving node in a communication network; determining if the digital signature is consistent with the unsecured video fingerprint at the receiving node to verify the unsecured video fingerprint; and determining if the unsecured video fingerprint is consistent with the unsecured video content at the receiving node to verify the unsecured video content in a manner that tolerates a predetermined measure of loss in the unsecured video content. If the unsecured video fingerprint and the unsecured video content are verified, the unsecured video content is authenticated for subsequent use at the receiving node. A receiving node associated with the method includes an input module, a fingerprint verification module, a content verification module, and a controller module.
