Researchers have developed a novel system called SSUPER for the MeViS-Text track of the LSVOS Challenge 2026, achieving a first-place ranking. This system excels at referring video object segmentation, accurately identifying objects based on textual descriptions, even when those descriptions indicate the absence of a target. SSUPER utilizes multiple large language models for reasoning and incorporates a multi-agent audit to distinguish between true absence and temporary invisibility, significantly improving the handling of 'no-target' expressions. Additionally, a StyleRefiner module aligns the mask geometry with the annotation style of MeViSv2 without altering presence decisions. AI
