MarsData-V2, a rock segmentation dataset of real Martian scenes

We release MarsData-V2, a rock segmentation dataset of real Martian scenes for the training of deep networks, extended from our previously published MarsData. The raw unlabeled RGB images of MarsData-V2 are from here, which were collected by a Mastcam camera of the Curiosity rover on Mars between August 2012 and November 2018. After sorting out images with an opportune shooting distance, labeling Mars rocks with fine-grained boundaries, and performing data augmentation referring to an earlier paper, we obtained 8390 labeled images with a resolution of 512 × 512, and divided them into 5040 images for training, 1680 for validation and 1670 for testing. Limited by the file size, we temporarily release 100 samples in the train, validation and test set of MarsData-V2, respectively. All samples will be provided after our paper is made public.
