Grain size of fluvial gravel bars from close-range UAV imagery – uncertainty in segmentation-based data

<p>Data on grain sizes of pebbles in gravel-bed rivers are of key importance for the understanding of river systems. To gather these data efficiently, low-cost UAV (uncrewed aerial vehicle) platforms have been used to collect images along rivers. Several methods to extract pebble size data fro...
