LOCUS model improves visual grounding with draft-and-verify approach

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new visual grounding model called LOCUS that improves accuracy by using a draft-and-verify approach. The model first generates a speculative bounding box using a regression head and then refines it through iterative coordinate-token verification. This method significantly reduces the number of sequential passes required to achieve precise localization compared to traditional coordinate-token decoding. On benchmark datasets like RefCOCO, RefCOCO+, and RefCOCOg, LOCUS demonstrated improved accuracy, particularly at higher Intersection over Union (IoU) thresholds, and showed competitive performance against other models in its parameter class.

    LOCUS: Locate Once, Check Until Settled. Draft-and-Verify Visual Grounding with a Box Head and Coordinate-Token Verification

    arXiv:2610.35053v1 Announce Type: new Abstract: Vision-language models (VLMs) ground a referring expression in one of two ways. They decode the box as coordinate tokens, which is precise but takes one sequential step per token, or they regress it from a hidden state with a small …
