Seafloor-Invariant Caustics Removal from Underwater Imagery
Panagiotis Agrafiotis, Konstantinos Karantzalos, Andreas Georgopoulos
Mapping the seafloor with underwater imaging cameras is of significant importance for various applications including marine engineering, geology, geomorphology, archaeology and bio…
Objects Can Move: 3D Change Detection by Geometric Transformation Constistency
Aikaterini Adam, Torsten Sattler, Konstantinos Karantzalos +1
AR/VR applications and robots need to know when the scene has changed. An example is when objects are moved, added, or removed from the scene. We propose a 3D object discovery meth…
What to Hide from Your Students: Attention-Guided Masked Image Modeling
Ioannis Kakogeorgiou, Spyros Gidaris, Bill Psomas +4
Transformers and masked language modeling are quickly being adopted and explored in computer vision as vision transformers and masked image modeling (MIM). In this work, we argue t…
Detecting Urban Changes with Recurrent Neural Networks from Multitemporal Sentinel-2 Data
Maria Papadomanolaki, Sagar Verma, Maria Vakalopoulou +2
\begin{abstract} The advent of multitemporal high resolution data, like the Copernicus Sentinel-2, has enhanced significantly the potential of monitoring the earth's surface and en…
Shallow Water Bathymetry Mapping from UAV Imagery based on Machine Learning
Panagiotis Agrafiotis, Dimitrios Skarlatos, Andreas Georgopoulos +1
The determination of accurate bathymetric information is a key element for near offshore activities, hydrological studies such as coastal engineering applications, sedimentary proc…
