no code implementations1 Aug 2021 Hannes Fassold, Antonis Karakottas, Dorothea Tsatsou, Dimitrios Zarpalas, Barnabas Takacs, Christian Fuhrhop, Angelo Manfredi, Nicolas Patz, Simona Tonoli, Iana Dulskaia

Spherical 360{\deg} video is a novel media format, rapidly becoming adopted in media production and consumption of immersive media.

Restyling Data: Application to Unsupervised Domain Adaptation

no code implementations24 Sep 2019 Vasileios Gkitsas, Antonis Karakottas, Nikolaos Zioulis, Dimitrios Zarpalas, Petros Daras

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 acquisition, which in some cases is very difficult or even impossible.

$360^o$ Surface Regression with a Hyper-Sphere Loss

2 code implementations16 Sep 2019 Antonis Karakottas, Nikolaos Zioulis, Stamatis Samaras, Dimitrios Ataloglou, Vasileios Gkitsas, Dimitrios Zarpalas, Petros Daras

We present a dataset of $360^o$ images of indoor spaces with their corresponding ground truth surface normal, and train a deep convolutional neural network (CNN) on the task of monocular 360 surface estimation.

OmniDepth: Dense Depth Estimation for Indoors Spherical Panoramas

1 code implementation ECCV 2018 Nikolaos Zioulis, Antonis Karakottas, Dimitrios Zarpalas, Petros Daras

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.
