CGHU-CD: A contrast-guided hierarchical unsupervised method for detecting Martian Anthropogenic Changes

The first benchmark dataset for Martian anthropogenic change detection (MACD) from bitemporal HiRISE imagery, encompassing four Mars exploration missions (Phoenix, Curiosity, Insight, and Perseverance) and multiple types of anthropogenic surface changes. Detailed image information can be found in our paper. The paper information will be released after can be accepted. The dataset includes two classes: rovers (and spacecraft components) and anthropogenic disturbance traces. Specifically, spacecraft components consist of heat shields, parachutes, and their parts. The green and red colors of the dataset denote the changed classes of rovers (and spacecraft components) and anthropogenic disturbance traces, respectively.
