New DualAnchor framework enhances sign language translation accuracy

Researchers have developed DualAnchor, a new framework for sign language translation (SLT) that aims to improve both the fluency of the translated text and the accuracy of lexical details. The framework addresses two key issues: language-prior degradation, where existing methods fail to leverage the full capabilities of large language models (LLMs), and a lexical fidelity gap, where sentence-level alignment misses fine-grained word accuracy. DualAnchor employs Token-level Prior Anchoring (TPA) to maintain the LLM's language prior and Optimal Transport Alignment (OTA) to enhance visual-textual matching, achieving strong performance on benchmark datasets like PHOENIX-2014T and CSL-Daily.
