New Technologies for A/V Analysis and Search


At this year’s NAB Show, the world’s largest convention for the digital media industry, taking place April 22–27, in Las Vegas, Fraunhofer IDMT will be presenting new technologies for A/V analysis and search. The updated tools allow users to detect partial duplicates, track metadata and content reuse, automatically extract metadata and manage complex multimodal analysis workflows.

A/V Segment Matching – Tracking metadata and detecting duplicates

The updated software tools of Fraunhofer IDMT compare audio content to identify duplicates and content reuse.

Aggregation, production and storage often include the creation of complete or partial copies of content, which results in unnecessary storage costs and issues related to metadata tracking. Fraunhofer IDMT’s audio and video segment technologies can be used to detect complete and partial matches as well as content reuse, which can also be a powerful tool for program analysis and content monitoring.

Automatic A/V annotation, now featuring audio forensics tools

Building on its existing A/V analysis technologies (amongst others speech-music discrimination and automatic audio/music and visual annotation), Fraunhofer IDMT now also provides several tools for audio forensics. “Our software tools support content production and avoid quality problems, for instance,” explains Patrick Aichroth, Head of Media Distribution and Security at Fraunhofer IDMT. “This can be achieved by using codec analysis to detect previous coding steps and parameters. Moreover, the tools allow the identification of the original recording device, which can be used to automatically adapt audio processing to the device’s properties”. Finally, if audio material was not properly annotated, the software helps finding cuts and edits.

An Open-Source Framework for multi-modal analysis and recommendation

The possibility to perform complex multi-modal content analysis is crucial to support advanced search and recommendation functionalities and to improve the quality of metadata, but it requires addressing of many technological challenges. The open-source framework MiCO (Media in Context), which was developed in a research project funded by the European Commission, addresses several of these challenges. The results and features of the project will be presented at NAB Show as well.

Automatic Quality Control (QC)

Fraunhofer IDMT will also present the integration of its QC components for automated Quality Control of DCP/IMF content into the professional movie post-production solution easyDCP by Fraunhofer IIS.

If you are interested in A/V Analysis and Search please feel free to stop by the Fraunhofer booth SU6110 in the South Upper Hall.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
