Dr. Hannes Mareen
Postdoc Researcher
Hannes is a Postdoctoral Researcher at IDLab-MEDIA. From 2017 until 2021, he pursued a PhD degree with the financial support of the Research Foundation - Flanders (FWO).
His research interests cover multimedia compression, security, and forensics. More specifically, his PhD research focused on video watermarking to trace digital pirates. He also researched image & video forgery detection, fingerprinting, perceptual hashing, optical character recognition, dense captioning, low-delay live streaming, medical image analysis and other applications.
Moreover, Hannes is enthusiastic about science communication targeted to non-experts. He won several awards, incl. the Agoriaprijs, two best poster awards (1, 2), the #ThesisThread competition, and the bronze trophy in the Vlaamse PhD Cup.
