Geo-NVS-w: Geometry-Aware Novel View Synthesis In-the-Wild with an SDF Renderer
Anastasios Tsalakopoulos, Angelos Kanlis, Evangelos Chatzis +2
We introduce Geo-NVS-w, a geometry-aware framework for high-fidelity novel view synthesis from unstructured, in-the-wild image collections. While existing in-the-wild methods alrea…
Image Valuation in NeRF-based 3D reconstruction
Grigorios Aris Cheimariotis, Antonis Karakottas, Vangelis Chatzis +2
Data valuation and monetization are becoming increasingly important across domains such as eXtended Reality (XR) and digital media. In the context of 3D scene reconstruction from a…
Hyper360 -- a Next Generation Toolset for Immersive Media
Hannes Fassold, Antonis Karakottas, Dorothea Tsatsou +7
Spherical 360° video is a novel media format, rapidly becoming adopted in media production and consumption of immersive media. Due to its novelty, there is a lack of tools for prod…
The Hyper360 toolset for enriched 360 video
Hannes Fassold, Antonis Karakottas, Dorothea Tsatsou +7
360 video is a novel media format, rapidly becoming adopted in media production and consumption as part of todays ongoing virtual reality revolution. Due to its novelty, th…
Restyling Data: Application to Unsupervised Domain Adaptation
Vasileios Gkitsas, Antonis Karakottas, Nikolaos Zioulis +2
Machine learning is driven by data, yet while their availability is constantly increasing, training data require laborious, time consuming and error-prone labelling or ground truth…
Spherical View Synthesis for Self-Supervised 360 Depth Estimation
Nikolaos Zioulis, Antonis Karakottas, Dimitrios Zarpalas +2
Learning based approaches for depth perception are limited by the availability of clean training data. This has led to the utilization of view synthesis as an indirect objective fo…
Surface Regression with a Hyper-Sphere Loss
Antonis Karakottas, Nikolaos Zioulis, Stamatis Samaras +4
Omnidirectional vision is becoming increasingly relevant as more efficient image acquisition is now possible. However, the lack of annotated datasets has hindered t…
A Low-Cost, Flexible and Portable Volumetric Capturing System
Vladimiros Sterzentsenko, Antonis Karakottas, Alexandros Papachristou +4
Multi-view capture systems are complex systems to engineer. They require technical knowledge to install and intricate processes to setup related mainly to the sensors' spatial alig…
OmniDepth: Dense Depth Estimation for Indoors Spherical Panoramas
Nikolaos Zioulis, Antonis Karakottas, Dimitrios Zarpalas +1
Recent work on depth estimation up to now has only focused on projective images ignoring 360 content which is now increasingly and more easily produced. We show that monocular dept…
