Unsupervised Learning Of Video Structures In Videos Using Hierarchical Statistical Models To Detect Events

View page
US Patent:
7313269, Dec 25, 2007
Filed:
Dec 12, 2003
Appl. No.:
10/734451
Inventors:
Lexing Xie - New York NY, US
Ajay Divakaran - Burlington MA, US
Shih-Fu Chang - New York NY, US
Assignee:
Mitsubishi Electric Research Laboratories, Inc. - Cambridge MA
International Classification:
G06K 9/62
US Classification:
382159, 7042561, 7042562
Abstract:
A method learns a structure of a video, in an unsupervised setting, to detect events in the video consistent with the structure. Sets of features are selected from the video. Based on the selected features, a hierarchical statistical model is updated, and an information gain of the hierarchical statistical model is evaluated. Redundant features are then filtered, and the hierarchical statistical model is updated, based on the filtered features. A Bayesian information criteria is applied to each model and feature set pair, which can then be rank ordered according to the criteria to detect the events in the video.

International Classification:
G06F 17/30
US Classification:
707755, 707791, 707999004
Abstract:
A method and apparatus is disclosed that receives an input narrative in a particular media format, and produces therefrom a multimedia enriched version of the input narrative. In one embodiment, a method is provided for enriching an input narrative with multimedia content, wherein the method includes the step of selectively segmenting the input narrative to form queries pertaining to different portions or elements of the input narrative. The method further comprises retrieving multimedia artifacts from one or more multimedia repositories, wherein each retrieved multimedia artifact is associated with one of the queries, and selecting a subset of the retrieved multimedia artifacts, wherein the subset includes artifacts comprising different types of multimedia content. The input narrative is then combined with respective multimedia artifacts of the subset, in order to provide an enriched and enhanced narrative.

US Patent:
8032539, Oct 4, 2011
Filed:
Mar 11, 2008
Appl. No.:
12/046206
Inventors:
Shahram Ebadollahi - White Plains NY, US

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 17/30
US Classification:
707754, 707748, 705 729, 705 267
Abstract:
The present invention is directed to a method and apparatus for assisting in rating and filtering multimedia content, such as images, videos and sound recordings. One embodiment comprises a computer implemented method for rating the objectionability of specified digital content that comprises one or more discrete content items, wherein the method includes the step of moving the specified content to one or more filtering stages in a succession of filtering stages. After the specified content is moved to a given one of the filtering stages, a rating procedure is carried out to determine whether a rating can be applied to one or more of the content items, and if so, a selected rating is applied to each of the one or more content items. The method further comprises moving content items of the specified content to the next stage in the succession after the given stage, when at least one content item of the specified content remains without rating, after the rating procedure at the given stage. When none of the content items of the specified content remains without a rating after the rating procedure has been completed at the given stage, ratings that have been respectively applied to at least some of the content items are selectively processed, in order to determine an overall objectionability rating for the specified content.

Structural Analysis Of Videos With Hidden Markov Models And Dynamic Programming

US Patent:
20030103565, Jun 5, 2003
Filed:
Dec 5, 2001
Appl. No.:
10/005623
Inventors:
Lexing Xie - New York NY, US
Shih-Fu Chang - New York NY, US
Ajay Divakaran - Denville NJ, US
Huifang Sun - Cranbury NJ, US
International Classification:
H04N007/12
US Classification:
375/240080, 375/240010, 375/240240, 375/240160
Abstract:
A method analyzes a high-level syntax and structure of a continuous compressed video according to a plurality of states. First, a set of hidden Markov models for each of the states is trained with a training video segmented into known states. Then, a set of domain specific features are extracted from a fixed-length sliding window of the continuous compressed video, and a set of maximum likelihoods is determined for each set of domain specific features using the sets of trained hidden Markov models. Finally, dynamic programming is applied to each set of maximum likelihoods to determine a specific state for each fixed-length sliding window of frames of the compressed video.

US Classification:
707739, 707740, 706 12, 707E17046, 706 54, 706 47, 707E17019
Abstract:
A system and method for constructing a hierarchical multi-faceted classification structure includes organizing a plurality of visual categories into a multi-relational reference ontology that accounts for a plurality of different types of relationships. Media artifacts are categorized into the plurality of visual categories. The categories of artifacts are refined based on faceted ontology relationships or constraints from the multi-relational reference ontology. The multi-relational reference ontology and the one or more media artifacts with relationships are stored as the hierarchical multi-faceted classification structure in computer readable memory storage.
