Scientific reports · Computational image-screening study
Researchers trained image-classification models to locate circular landscape patterns in satellite imagery. The study presents a way to screen large areas for candidates requiring further investigation.
Method and scope
Pre-trained convolutional neural networks were applied to geomorphological imagery and evaluated for pattern detection.
What to keep in mind
A detected circular feature is not proof of natural hydrogen or a particular ecological mechanism. Different kinds of circular features require field verification.
