REBASE: Reference-Background Subspace Elimination for Training-Free In-Context Segmentation
This paper identifies the low-rank background feature subspace from the reference image and project the reference and query features onto its orthogonal complement in closed form, yielding cleaner semantic matching, and establishes a new state of the art among training-free methods on PACO-Part, FSS-1000, and cross-dom...
