The TOSCA-MP test & demonstration workshop was held at the EBU headquarters in Geneva on June 4th. Participants were able to test and evaluate software components that have been created in the run of the project as well as give their opinion and feedback about the developed scenarios. The workshop was attended by about 15 professionals from 5 public broadcasters.

After an introduction to the project and a presentation on the business goals and scenarios, that guide the technical developments, the participants could see demos of different software components and try them hands on. The control & config user interface serves as a central hub for monitoring the status of content repositories and invoking workflows for automatic information extraction.
The user interface for result verification and assessment visualizes results of a range of automatic video quality analysis algorithms are. An exploratory-based search user interface supports different visual functionalities for query refinement and enhancement. It relies on Semantic Web technologies and combines content-related features and semantic descriptors to improve the accuracy and recall of the search results. It also allows search and filtering based on automatic annotations.

Valuable feedback from the participants has been gathered in questionnaires and discussions. The received feedback is currently processed and will be summarised in a report by July 2013. It will serve as an important input for the development in the final development cycle of the project.

TOSCA-MP will organise a test workshop on June 4, 2013 in Geneva, hosted by EBU.

During this field trial day, taking place prior to the EBU Metadata Developer Network (MDN) workshop, you will be able to test and evaluate software components that have been created in the run of the project as well as give your opinion and feedback about the developed scenarios.
Your feedback will be very valuable information for the consortium to further improve the TOSCA-MP tools and services in a future iteration. This is an overview of the tools available for testing:

  • The control & config user interface serves as a central hub for monitoring the status of content repositories and invoking workflows for automatic information extraction.
  • The user interface for result verification and assessment visualizes results of a range of automatic video quality analysis algorithms are. The tool provides efficient means for navigating the analysis results, and verifying and correcting detected defects, as well as adding further annotations.
  • An exploratory-based search user interface that supports different visual functionalities for query refinement and enhancement. The tool relies on Semantic Web technologies and combines content-related features and semantic descriptors to improve the accuracy and recall of the search results. It also allows search and filtering based on automatic annotations.

The full programme is available for download here. For information about hotels see the EBU MDN page.

After two successful editions, the Third Video Browser Showdown will be held in conjunction with MMM 2014 in Dublin, Ireland. The Video Browser Showdown (VBS) is an annual live video browsing competition where international researchers, working in the field of interactive video search, evaluate and demonstrate the efficiency of their tools. For more information, see the VBS website. As in previous years, TOSCA-MP will co-organise the competition and provide data sets.

Pilot field trials to assess quality metrics

Prior to the 1st EC review of TOSCA-MP in Feb. 2012 in Brussels, a pilot field trial was performed in order to assess prototypes of quality analysis tools developed in the project. The field trial was hosted by the Flemish broadcasting corporation (VRT), and 28 of their experts volunteered to participate in the two-part experiment.

First they were asked to rate the perceived sharpness of several viewed videos without any reference and then they compared two consecutively watched videos on a discrete comparison scale. Additionally, half of all tests were accomplished with an eye tracking system. For a better understanding on how people perceive the quality of a video and which parts are prioritized for judging the quality of a video sequence, we analyze the eye-tracking data and the resulting regions of interest obtained during scoring image quality. The resulting mean opinion scores of human perception are used to validate the sharpness algorithm which is one of several objective quality metrics that are developed within TOSCA-MP. Many thanks to all staff members of the Flemish public broadcasting company VRT who kindly participated in the subjective experiments!

Successful Video Browser Showdown 2013

Like in 2012, TOSCA-MP co-organised the Video Browser Showdown as a session of the MMM 2013 conference, held from Jan. 7-9 in Huangshan, China. The Video Browser Showdown is a live video browsing competition where international researchers, working in the field of interactive video search, evaluate and demonstrate the efficiency of their tools in presence of the audience. The aim of the Video Browser Showdown is to evaluate video browsing tools for their efficiency at “Known Item Search” (KIS) tasks with a well-defined data set in direct comparison with other tools. For each KIS task the searchers of the six participating teams from Europe and Asia need to interactively find a short video clip in a one-hour video file within a specific time limit.

Like in 2012, TOSCA-MP provided content collected by its archive partners on the MAMMIE platform and helped organising the competition. There were two rounds of the competition, one with expert users, the other one with novice users from the audience. The analysis of the search and some system logs of the 2012 competition was presented as a paper in the MMM 2013 main conference, and we are confident, that the analysis of the results of the 2013 competition again provides interesting insights.

TRECVID is one of the most important benchmarking initiatives for automatic segmentation, indexing, and content-based retrieval of digital video. JOANNEUM RESEARCH has been participating in TRECVID for many years. This year, at the anniversary 10th TRECVID workshop, we have participated using results of our work in TOSCA-MP.

A poster presented at the workshop gives an overview of the work done for the Semantic Indexing and Instance Search tasks, and a presentation gives more details on the approach and results for the Instance Search task.

Georg Thallinger from JOANNEUM RESEARCH will present a paper titled “A System for Task-Oriented Content Analysis and Search in Media Production” in Session 2B – Connected Media Worlds II of the NEM Summit 2012 in Istanbul on Oct. 17th. The paper discusses the use cases, scenarios and tasks addressed in the TOSCA-MP project and its SOA-based system architecture.

A TOSCA-MP overview poster will be presented at the NEM Summit exhibition at the booth of the FascinatE project.
