Computer Vision, Perception and Cognition Group
«KI ist DIE Schlüsseltechnologie des digitalen Wandels in allen Branchen und Sektoren und sie hat starke Auswirkungen auf unsere Gesellschaften. Darum leistet unsere Forschung wichtige Beiträge zu robusten und vertrauenswürdigen KI-Methoden, und wir vermitteln mit Begeisterung deren sichere Umsetzung und Anwendung.»
Expertise
- Mustererkennung mit Deep Learning
- Maschinelle Wahrnehmung, Computer Vision und Sprechererkennung
- Entwicklung neuronaler Systeme
Die Computer Vision, Perception and Cognition-Gruppe forscht über Mustererkennung und arbeitet an einer Vielzahl von Aufgaben mit Bild-, Ton- oder allgemein Signaldaten. Wir befassen uns mit der Methodik der tiefen neuronalen Netze (Deep Neural Networks) und des Reinforcement Learning, inspiriert durch biologisches Lernen. Jede unserer Aufgaben hat ihr eigenes Lernziel (z. B. Erkennung, Klassifizierung, Clustering, Segmentierung, Novelty Detection, Steuerung) und ihren eigenen Anwendungsfall (z. B. vorausschauende Instandhaltung (Predictive Maintenance), Sprechererkennung für Multimedia-Indizierung, Dokumentanalyse, optische Notenerkennung, Computer Vision für industrielle Qualitätskontrolle, automatisiertes maschinelles Lernen, Deep Reinforcement Learning für automatisierte Spiele oder Gebäudeleittechnik). Diese werfen ihrerseits ein Licht auf verschiedene Aspekte des Lernprozesses. Wir nutzen diese Erfahrungen, um allgemeinere KI-Systeme zu kreieren, die auf neuronalen Architekturen basieren.

AUTODIDACT – Automated Video Data Annotation to Empower the ICU Cockpit Platform for Clinical Decision Support
Monitoring diverse sensor signals of patients in intensive care can be key to detect potentially fatal emergencies. But in order to perform the monitoring automatically, the monitoring system has to know what is currently happening to the patient: if the patient is for example currently being moved by medical staff, ...

Accessible Scientific PDFs for All
PDF is the most popular document format to provide and distribute information on the internet. It was developed by Adobe 1996 but has been an open format since 2008. It was estimated in 2015 that more than 2.5 trillion PDF documents exist on the internet, covering all aspects of life and research, and their number ...

Synthetic data generation of CoVID-19 CT/X-rays images for enabling fast triage of healthy vs. unhealthy patients
The automatic analysis of X-ray/CT images through artificial intelligence models can be useful to automate the clinical scanning procedure. Nonetheless, the limited access to real COVID patient data leads to the need of synthesizing image samples. The goal of this project is to use existing CT/X-ray image datasets ...

Standardized Data and Modeling for AI-based CoVID-19 Diagnosis Support on CT Scans (SDMCT)
Hospitals and research institutes are highly investigating applications of AI in medical imaging. However, developed models and datasets are barely mergeable, and the research results are not reproducible on different datasets due to different CT scanners used. Radiologists told us that “unifying data is crucial for ...

DIR3CT: Deep Image Reconstruction through X-Ray Projection-based 3D Learning of Computed Tomography Volumes
Project DIR3CT aims at improving the image quality of CBCT images by deep learning (DL) the 3D reconstruction from X-ray images end-to-end. This enables a novel CBCT product to be used during radiation therapy and will allow the use of these images for adaptive treatment.
