Evaluating Whole-Sky Cloud Segmentation Against an Operating Solar Station: The CLOUD99 Dataset and Protocol
Ground-based whole-sky imagers provide cloud cover data to determine solar observing conditions. Deep segmentation models exceed 0.87 mean intersection-over-union (IoU, shared area over union) on public benchmarks, but need not transfer to an operating site. We release CLOUD99, a dataset of 99 annotated whole-sky image...
