Abstract With the progress of Mars exploration, numerous Mars image data are collected and need to be analyzed. However, because of the imbalance and distortion in Mars data, the performance of existing classification models is unsatisfactory. In this paper, we design a new framework based on semi-supervised contrastive learning for Mars rover image classification. The redundancy of Mars data can disable the effectiveness of contrastive learning. To strip out problematic learning samples, we propose to ignore inner-class pairs on labeled data as well as neglect negative pairs on unlabeled data. Experimental results show that our learning strategies can improve the classification model by a large margin and outperform state-of-the-art methods.
