Call for Participation in TRECVID 2020


CALL FOR PARTICIPATION in the
2020 TREC VIDEO RETRIEVAL EVALUATION (TRECVID 2020)

February 2020 - November 2020

Conducted by the National Institute of Standards and Technology (NIST)
with additional funding from other US government agencies.

I n t r o d u c t i o n:

The TREC Video Retrieval Evaluation series (trecvid.nist.gov) promotes
progress in content-based analysis of and retrieval from digital video
via open, metrics-based evaluation. TRECVID is a laboratory-style
evaluation that attempts to model real world situations or significant
component tasks involved in such situations. In its 20th annual evaluation
cycle TRECVID will evaluate participating systems on 6 different video
analysis and retrieval tasks using various types of real world datasets.
Below is the main datasets to be used in 2020 across the 6 proposed tasks.

D a t a:

In TRECVID 2020 NIST will use at least the following data sets:

      * Vimeo Creative Commons Collection (V3C)
     
      The V3C is a large-scale video dataset that has been collected from high-quality 
      web videos with a time span over several years in order to represent true videos 
      in the wild. It consists of 28,450 videos with a duration of 3,801 hours in total. 
      The first part of this dataset (V3C1) has been used by the Video Browser Showdown 
      (VBS) 2019 and the Ad-Hoc Video Search (AVS) task at TRECVID 2019 as well. 
      For both campaigns V3C1 will serve as a basis over three years (VBS 2019-2021 
      and TRECVID 2019-2021). V3C1 contains 1,000 hours of video content and approximately one million 
      shots that were created by the authors of the dataset using the open-source multimedia 
      retrieval engine Cineast. A subset of approx. 2000 clips from the second part (V3C2) of the V3C
      collection will be used as testing data for the Video-to-Text (VTT) task in 2020.
      
      * IACC.3

      The IACC.3 was introduced in 2016 and consists of approximately 4600 Internet 
      Archive videos (144 GB, 600 h) with Creative Commons licenses in MPEG-4/H.264
      format with duration ranging from 6.5 min to 9.5 min and a mean duration
      of almost 7.8 min. Most videos will have some metadata provided by the
      donor available e.g., title, keywords, and description.

      * BBC EastEnders

      Approximately 244 video files (totally 300GB, 464 hours) with
      associated metadata, each containing a week's worth of BBC EastEnders
      programs in MPEG-4/H.264 format.

      * Twitter Vine videos
   
      Approximately 8,000 6 sec video clips URLs from the public Twitter stream of Vine videos 
      have been human annotated by video captions from 2016-2019. These Vine videos will be provided
      as development data for participants of the Video-to-Text (VTT) task.


      * Gatwick and i-LIDS MCT airport surveillance video

      The data consist of about 150 hours obtained from airport
      surveillance video data (courtesy of the UK Home Office). The
      Linguistic Data Consortium has provided event annotations for
      the entire corpus. The corpus was divided into development and
      evaluation subsets. Annotations for 2008 development and test
      sets are available.

      * VIRAT dataset
  
      The VIRAT Video Dataset is a large-scale surveillance video dataset designed to 
      assess the performance of activity detection algorithms in realistic scenes. 
      The dataset was collected to facilitate both detection of activities and to localize 
      the corresponding spatio-temporal location of objects associated with activities from 
      a large continuous video. The VIRAT dataset are closely aligned with real-world video 
      surveillance analytics.

       * LADI dataset

      The Low Altitude Disaster Imagery (LADI) dataset is hosted as part of the AWS Public Dataset program 
      and will be available to participants of the DSDI task as development data. It consists of over 20,000+ 
      annotated images, each at least 4 MB in size. The annotated features were selected based on a recommendation 
      from the public safety community. In total there are 31 features across 5 categories. The dataset was 
      collected between 2015 - 2019 during major natural disaster events (e.g. hurricanes, floodings, earthquakes) 
      across several USA states. The lower altitude criteria is intended to further distinguish the LADI dataset 
      from satellite or "top down" datasets and to support development of computer vision capabilities 
      for small drones operating at low altitudes. A minimum image size was selected to maximize the efficiency 
      of the crowd source workers. For more information about LADI, please refer to the 
      github organization.


T a s k s:

In TRECVID 2020 NIST will evaluate systems on the following tasks
using the [data] indicated:


    * AVS: Ad-hoc Video Search (automatic, manually-assisted, relevance feedback) [V3C1]

      The Ad-hoc search task started in TRECVID 2016 and will continue in 2020 
      to model the end user search use-case, who is looking for 
      segments of video containing persons, objects, activities, locations, etc., 
      and combinations of the former. Given about 30 multimedia topics created at 
      NIST, return for each topic all the shots which meet the video need expressed 
      by it, ranked in order of confidence. Although all evaluated submissions will be
      for automatic runs, Interactive systems will have the opportunity to
      participate in the Video Browser Showdown (VBS) in 2021 using 
      the same testing data (V3C1).


    * ActEV: Activities in Extended Video [VIRAT]
      
      ActEV is a series of evaluations to accelerate development of robust, multi-camera, 
      automatic activity detection algorithms for forensic and real-time alerting applications. 
      ActEV is an extension of the annual TRECVID Surveillance Event Detection (SED) evaluation 
      where systems will also detect, and track objects involved in the activities. Each evaluation 
      will challenge systems with new data, system requirements, and/or new activities.

      
    * INS: Instance search (interactive, automatic) [BBB EastEnders] 

      An important need in many situations involving video collections
      (archive video search/reuse, personal video organization/search,
      surveillance, law enforcement, protection of brand/logo use) is to
      find more video segments of a certain specific person, object,
      or place, given a visual example. A new query type started in 2019 
      asking systems to retrieve specific persons doing specific actions. 
      A set of defined actions with various image/video examples will be given 
      and each topic will include few examples (image and video) 
      of a person and ask systems to find that person doing one of the defined actions.

    * VTT: Video to Text Description [Vimeo Creative Commons Collections (V3C2)]

      Automatic annotation of videos using natural language text descriptions 
      has been a long-standing goal of computer vision. The task involves 
      understanding of many concepts such as objects, actions, scenes, person-object 
      relations, temporal order of events and many others. In recent years there have 
      been major advances in computer vision techniques which enabled researchers to 
      start practically to work on solving such problem. 
      Given a set of short video clips and number of reference sets of text descriptions, 
      systems are asked to work and submit results for two subtasks.The core "Description Generation" subtask requires
      systems to automatically generate a text description (1 sentence) for each video clip.
      An optional "Matching and Ranking" subtask requires systems to
      return for each video a ranked list of the most likely text
      description that correspond (was annotated) to the video from each of the reference sets.

    * VSUM: Video Summarization [BBC Eastenders Soap Opera]
      An important need in many situations involving video collections (archive video search/reuse, 
      personal video organization/search, movies, tv shows, etc.) is to summarize the video in order 
      to reduce the size and concentrate the amount of high value information in the video track. 
      In 2020 we begin a new video summarization track in TRECVID in which the task is to
      summarize the major life events of specific characters over a number of weeks of programming 
      on the BBC Eastenders TV series. Typically, three characters will be chosen for this task every year, 
      and summaries of their major life events must be between the selected period of the show, which will 
      be specified to participants in advance of the task.

* DSDI: Disaster Scene Description and Indexing [Low Altitude Disaster Imagery (LADI)] Computer vision capabilities have rapidly been advancing and are expected to become an important component to incident and disaster response. However, the majority of computer vision capabilities are not meeting public safety needs, such as support for search and rescue, due to the lack of appropriate training data and requirements. In response, the organizers developed a dataset of images collected by the Civil Air Patrol of various natural disasters. Two key distinctions are the low altitude and oblique perspective of the imagery and disaster-related features, which are rarely featured in computer vision benchmarks and datasets. This task invites researchers to work on this new domain to develop new capabilities and close the gap in performance to essentially label short video clips with the correct disaster-related feature(s). In addition to the data, TRECVID will provide uniform scoring procedures, and a forum for organizations interested in comparing their approaches and results. Participants will be encouraged to share resources and intermediate system outputs to lower entry barriers and enable analysis of various components' contributions and interactions. *************************************************** * You are invited to participate in TRECVID 2020 * *************************************************** The evaluation is defined by the Guidelines. A draft version is available: http://www-nlpir.nist.gov/projects/tv2020/index.html and further feedback input from the participants are welcomed till April,2020. You should read the guidelines carefully before applying to participate in one or more tasks: Guidelines P l e a s e n o t e: 1) Dissemination of TRECVID work and results other than in the (publicly available) conference proceedings is welcomed, but the conditions of participation specifically preclude any advertising claims based on TRECVID results. 2) All system output and results submitted to NIST are published in the Proceedings or on the public portions of TRECVID web site archive. 3) The workshop is open only to participating groups that submit results for at least one task and to selected government personnel from sponsoring agencies and data donors. 4) Each participating group is required to submit before the November workshop a notebook paper describing their experiments and results. This is true even for groups who may not be able to attend the workshop. 5) It is the responsibility of each team contact to make sure that information distributed via the call for participation and the tv20.list@list.nist.gov email list is disseminated to all team members with a need to know. This includes information about deadlines and restrictions on use of data. 6) By applying to participate you indicate your acceptance of the above conditions and obligations. There is a tentative schedule for the tasks included in the Guidelines webpage: Schedule W o r k s h o p f o r m a t Plans are for a 2 and half days workshop at NIST in Gaithersburg, Maryland - just outside Washington, DC. Confirmation and details will be provided to participants as soon as available. The TRECVID workshop is used as a forum both for presentation of results (including failure analyses and system comparisons), and for more lengthy system presentations describing retrieval techniques used, experiments run using the data, and other issues of interest to researchers in information retrieval and computer vision. As there is a limited amount of time for these presentations, the evaluation coordinators and NIST will determine which groups are asked to speak and which groups will present in a poster session. Groups that are interested in having a speaking slot during the workshop will be asked to submit a short abstract before the workshop describing the experiments they performed. Speakers will be selected based on these abstracts. H o w t o r e s p o n d t o t h i s c a l l Organizations wishing to participate in TRECVID 2020 must respond to this call for participation by submitting an on-line application by 1 April (the earlier the better). Only ONE APPLICATION PER TEAM please, regardless of how many organizations the team comprises. *PLEASE* only apply if you are able and fully intend to complete the work for at least one task. Taking the data but not submitting any runs threatens the continued operation of the workshop and the availability of data for the entire community. Here is the application URL: http://ir.nist.gov/tv-submit.open/application.html You will receive an immediate automatic response when your application is received. NIST will respond with more detail to all applications submitted before the end of March. At that point you'll be given the active participant's userid and password, be subscribed to the tv20.list email discussion list, and can participate in finalizing the guidelines as well as sign up to get the data, which is controlled by separate passwords. T R E C V I D 2 0 2 0 e m a i l d i s c u s s i o n l i s t The tv20.list email discussion list (tv20.list@list.nist.gov) will serve as the main forum for discussion and for dissemination information about TRECVID 2020. It is each participant's responsibility to monitor the tv20.list postings. It accepts postings only from the email addresses used to subscribe to it. At the bottom of the guidelines there is a link to an archive of past postings available using the active participant's userid/password. Q u e s t i o n s Any administrative questions about conference participation, application format/content, subscriptions to the tv20.list, etc. should be sent to george.awad at nist.gov.
