专题命中 跨模态检索 :multi-modal(title,abstract);分类 cs.CV、cs.AI

AI总结 本文提出模态隔离门控融合(MIGF)方法,通过独立编码流和门控阶段提升多模态前列腺MRI分割的鲁棒性,实验表明其在不同模态缺失和伪影情况下均有效。

Comments Major revision. Single-fold analysis replaced by 5-fold cross-validation (180 trained models) plus a direct gate-mechanism analysis; conclusions updated to show that modality gating is backbone-conditional. Supersedes v1
