Change Detection in VHR Imagery With Severe Co-Registration Errors Using Deep Learning: A Comparative Study

1 code implementation IEEE Access 2022 Viktoria Kristollari, Vassilia Karathanassi

Based on that, the goal of this study is to evaluate the performance of five state-of-the-art DL CD methods, two unsupervised and three supervised, on VHR images with severe co-registration errors.

Artificial neural networks for cloud masking of Sentinel-2 ocean images with noise and sunglint

1 code implementation26 Jan 2020 Viktoria Kristollari, Vassilia Karathanassi

It was shown that the ANNs trained on the second dataset perform very favourably, in contrast to the ANNs trained on the first dataset that fails to adequately represent the spectra of the noisy Sentinel-2 images.
