Dataset and model for the paper "Tackling Small Lunar Impact Crater Classification: A Novel Augmented Dataset and Enhanced Deep Learning Framework"

We developed the Small Crater Augmented Dataset (SCAD), employing advanced data augmentation strategies to address class imbalance, notably enhancing representation of rare morphologies (flat-bottomed craters, central mounds, and concentric craters). The model integrates focus loss to mitigate class imbalance and adopts efficient intersection-over-union ratio optimisation to enhance boundary detection accuracy.
