ACCV Special Session: RGB-D (Xbox-Kinect) application competition

http://www.accv2012.org/sub/sub02_05.asp

The goal of this special session is to provide a platform for computer vision researchers to present their recent works, preliminary ideas and/or results related to RGB-D cameras. We provide prize awards for the first prize (USD$800) and first runner-up (USD$200) to encourage high quality submission to this special session. The competition is a peer evaluated competition. Each participant will be asked to give a poster presentation and/or demo during the special session event in the ACCV2012. The attendants of ACCV 2012 will vote for the winner of this competition.

We encourage re-submission of high quality works accepted/presented from other conferences/journals. Papers submitted to the ACCV main conferences are also welcome to submit their works to this special session. The proposals accepted to this special session are not considered as regular papers in ACCV.

What to submit:

Each team should submit a 1-2 page proposal via the special session registration website. The format of proposal is the same as the ACCV paper submission format. The submitted proposals will be included in the ACCV proceedings as a record of this special session competition.

Important Date:

August 24, 2012 Submissions Deadline

September 30, 2012 Notification of acceptance

November 6, 2012 Special Session event in ACCV

November 7-9, 2012 ACCV Main Conference

Content-Based Analysis Improves Audiovisual Archive Retrieval

Original Article: http://www.ceessnoek.info/

The paper “Content-Based Analysis Improves Audiovisual Archive Retrieval” by Bouke Huurnink, Cees Snoek, Maarten de Rijke, and Arnold Smeulders, which appears in the August issue of IEEE Transactions on Multimedia, is now available. Content-based video retrieval is maturing to the point where it can be used in real-world retrieval practices. One such practice is the audiovisual archive, whose users increasingly require fine-grained access to broadcast television content. In this paper, we take into account the information needs and retrieval data already present in the audiovisual archive, and demonstrate that retrieval performance can be significantly improved when content-based methods are applied to search. To the best of our knowledge, this is the first time that the practice of an audiovisual archive has been taken into account for quantitative retrieval evaluation. To arrive at our main result, we propose an evaluation methodology tailored to the specific needs and circumstances of the audiovisual archive, which are typically missed by existing evaluation initiatives. We utilize logged searches, content purchases, session information, and simulators to create realistic query sets and relevance judgments. To reflect the retrieval practice of both the archive and the video retrieval community as closely as possible, our experiments with three video search engines incorporate archive-created catalog entries as well as state-of-the-art multimedia content analysis results. A detailed query-level analysis indicates that individual content-based retrieval methods such as transcript-based retrieval and concept-based retrieval yield approximately equal performance gains. When combined, we find that content-based video retrieval incorporated into the archive’s practice results in significant performance increases for shot retrieval and for retrieving entire television programs. The time has come for audiovisual archives to start accommodating content-based video retrieval methods into their daily practice.

Fusing Concept Detection and Geo Context for Visual Search

Article from http://www.ceessnoek.info/index.php/fusing-concept-detection-and-geo-context-for-visual-search/

The ICMR2012 paper Fusing Concept Detection and Geo Context for Visual Search by Xirong Li, Cees Snoek, Marcel Worring and Arnold Smeulders is now available. Given the proliferation of geo-tagged images, the question of how to exploit geo tags and the underlying geo context for visual search is emerging. Based on the observation that the importance of geo context varies over concepts, we propose a concept-based image search engine which fuses visual concept detection and geo context in a concept-dependent manner. Compared to individual content-based and geo-based concept detectors and their uniform combination, concept-dependent fusion shows improvements. Moreover, since the proposed search engine is trained on social-tagged images alone without the need of human interaction, it is flexible to cope with many concepts. Search experiments on 101 popular visual concepts justify the viability of the proposed solution. In particular, for 79 out of the 101 concepts, the learned weights yield improvements over the uniform weights, with a relative gain of at least 5% in terms of average precision.

OCiRis Project

http://chatzichristofis.info/?page_id=451

OCiRis is a new open source (student project) application for OCR on Android. Use your mobile phone to convert the printed text into an electronic and searchable format.

[Download Files][Download APK]

User Instructions
  • Open the application “Character Recognition”.
  • Aim the word with the camera. Be careful to align with the red line.

  • Touch the screen, then you do not need to focus to the word as the screen is frozen.

  • Drag your finger on the screen to mark the word.

  • If the word is not right after the character recognition go to step 2.
  • If the word is right press the button “google it!!!”

How to install the application to your Android device
  1. Put the [Application] into your SD card.
  2. Download ASTRO File Manager to your device. You can find it on Play Store.
  3. Open ASTRO File Manager and choose “MANAGE MY FLES”
  4. Choose the .apk file from your SD card and press install.
  5. Now OCiRis is running to your phone!
How to run the application from eclipse
  1. Download eclipse indigo (http://www.eclipse.org/downloads/).
  2. Download the latest JDK (http://www.oracle.com/technetwork/java/javase/downloads/index.html) and SDK (http://developer.android.com/sdk/index.html) and make the proper settings on eclipse (http://developer.android.com/sdk/installing/index.html , http://developer.android.com/sdk/eclipse-adt.html and http://developer.android.com/sdk/installing/adding-packages.html )
  3. Create a Android Virtual Device (http://developer.android.com/training/basics/firstapp/running-app.html )
  4. Install C/C++ Development Tools in eclipse (http://archive.eclipse.org/technology/phoenix/demos/install-cdt/callisto-cdt.html ).
  5. Import into your workspace the OCiRis.zip , the tess-two.zip and the OpenCV.zip from the folder “Eclipse exports”.
  6. Close Eclipse and re-open it to save the changes from workspace.
  7. Now you can see and work on our code.
