Mars-Bench: mb-landmark_cls

This is a multi-class classification dataset derived from orbital HiRISE imagery. It classifies into 8 surface feature classes: Bright Dune, Crater, Dark Dune, Impact Ejecta, Slope Streak, Spider, Swiss Cheese, and Other. The class distribution is highly imbalanced, with “Other” comprising the majority of samples and Impact Ejecta being the minority class. Landmarks were extracted using a dynamic salience-based method. Labels were generated via a mix of volunteer crowdsourcing and expert validation, with additional calibration techniques applied to improve reliability.
