Main Research Topics

For many years, Fraunhofer IDMT has been conducting research and development in the fields of audio-visual signal processing and analysis, machine learning and the associated data protection and security aspects. Currently, the researchers investigate to what extent these established analysis methods from the broadcasting sector can be adapted and applied to industrial applications.

At regular intervals, the scientists exchange information with industry representatives and present current research results at scientific conventions.
