SAM 3 can be applied training-free to remote sensing open-vocabulary segmentation and change detection by fusing its semantic and instance heads and filtering with presence scores.
ProC-SAM3 builds a curated per-dataset prompt pool with an MLLM, caches text embeddings, and fuses SAM 3 mask outputs through a presence gate, reaching 56.1% average mIoU on eight remote-sensing benchmarks.
