Corsel, C.W. (author), van Lier, M. (author), Kampmeijer, L. (author), Boehrer, N. (author), Bakker, E.M. (author)In surveillance applications, the detection of tiny, lowresolution objects remains a challenging task. Most deep learning object detection methods rely on appearance features extracted from still images and struggle to accurately detect tiny objects. In this paper, we address the problem of tiny object detection for real-time surveillance...conference paper 2023

Boehrer, N. (author), Nieuwenhuizen, R.P.J. (author), Dijk, J. (author)Long-range horizontal path imaging through atmospheric turbulence is hampered by spatiotemporally randomly varying shifting and blurring of scene points in recorded imagery. Although existing software-based mitigation strategies can produce sharp and stable imagery of static scenes, it remains highly challenging to mitigate turbulence in scenes...article 2021

Boehrer, N. (author), Gabriel, A. (author), Brandt, A. (author), Uijens, W.R. (author), Kampmeijer, L. (author), van der Stap, N. (author), Schutte, K. (author)With the latest advances in image sensor technology, cameras are able to generate video with tens of megapixels per frame. These high resolution videos streams offer great potential to be used in the surveillance domain. For ground based systems, gigapixel streams are already used with great effect as illustrated by the ICME 2019 crowd counting...conference paper 2020

Boehrer, N. (author), Nieuwenhuizen, R.P.J. (author), Dijk, J. (author)Long range horizontal path imaging through atmospheric turbulence is hampered by spatiotemporally randomly varying shifting and blurring of scene points in recorded imagery. Typical mitigation strategies employ software algorithms that combine optical flow to estimate and reduce tip/tilt aberrations with lucky patch identification and data...conference paper 2019
