In Fall 2023, I fine-tuned the Segment Anything Model (SAM) to produce robust terrain segmentation masks for Mars 2020 Rover imagery in Mastcam-Z and Navcam images to support enhanced image stitching and spectral contrast in a Unity based observation planning tool used by the Mastcam-Z Operations Engineers and Scientists called Viewpoint. The fine-tuned model has been deployed since fall 2023 without requiring retraining to date (July 2025), producing segmentation masks upon image downlink to support daily operations shifts. Fine-tuning used pytorch and lightning on a A-100 80GB gpu with the huggingface implementation of SAM and Weights and Biases for experiment tracking.
