A/V Analyzing Toolbox for Automatic Quality Control and Efficient Management of A/V Content

03.04.2014

At NAB Show, the world’s largest convention for the digital media industry, taking place April 7 - 10 in Las Vegas, Nevada (USA), Fraunhofer IDMT will be presenting the latest developments of its software toolbox for automatic ana-lysis of digital audio and video content. The A/V Analyzing Toolbox comes with a broad range of components, which allow to significantly improve content production, distribution, and archiving processes.

Assessing the quality of audio and video content


The A/V Analyzing Toolbox provides automatic detection of audio-visual errors on signal level.

Fraunhofer IDMT

The software components for automatic quality control allow fast identification of quality problems in digital audio and video recordings. With the »Quick Scan« module large databases can be searched through very fast in order to detect typical errors, such as blocking, blurring, or ringing. In addition, the institute presents its improved analyzing method to proof the field order/field dominance for each video frame.

“Our tools for continuous quality control help film producers or broadcasters ensure that audio and video content is error-free already during the production process. Content can then be edited, distributed and archived more efficiently, as all related processes are automated”, says Dr. Uwe Kühhirt, head of the Audiovisual Systems group at Fraunhofer IDMT.

Detection of speech and music 

The module for automatic speech/music discrimination allows determination of the amount of music, speech, speech together with background music, and silence in radio and TV programs. This can be used for automatic music royalty reporting, cue sheet generation, or content search.

Segment-based video identification

Using this module, it is possible to identify video segments that originate from the same recording or source. Dr. Uwe Kühhirt explains the principle of segment-based video identification: “With our method, compact representations, so-called fingerprints, are generated from the video material. These fingerprints can then be compared to each other in a multi-stage, automated process in order to find those segments in the video recording that originally come from a certain source.”

The method cannot only be used to determine if and where a video segment has been reused, but also how long this segment is and at which position within a longer se-quence it has been inserted. It is also possible to find out if content has been manipu-lated, how much of the content has been used, and where it has been reused. 

The method for segment-based video identification has been developed in “CUbRIK”, a reseach and development project funded by the European Commission, where Fraunhofer IDMT is participating as a research partner. The aim of the project is to de-velop an intelligent framework for multimedia search that takes into account the knowledge and the skills of users to optimize the results of automated methods of analysis.

The A/V Analyzing Toolbox is completed by the module for Temporal Video Segmenta-tion, by which shots and representative key frames in movies can be identified in order to be able to search for and manage content more easily. Based on the information gained from this, e.g. rhythmical patterns in movies can be analyzed. Integrated motion analysis allows detection and classification of local and global motion in videos (e.g. pans, tilts, or zooms).

Im Focus: Hubble survey unlocks clues to star birth in neighboring galaxy

In a survey of NASA's Hubble Space Telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass.

By nailing down what percentage of stars have a particular mass within a cluster, or the Initial Mass Function (IMF), scientists can better interpret the light...

Im Focus: How wind sculpted Earth's largest dust deposit

China's Loess Plateau was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to a new report from University of Arizona geoscientists. The study is the first to explain how the steep-fronted plateau formed.

Im Focus: An engineered surface unsticks sticky water droplets

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.

Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...

Im Focus: Increasingly severe disturbances weaken world's temperate forests

Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.

"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
