文章背景与核心概要
当前的开放词汇实例分割(OVIS)和开放集全景分割(OSPS)方法在面对带噪的伪掩码、有限的视觉-文本基础对齐以及处理同义词或词表外(OOV)词汇时,往往表现出明显的局限性。本文针对这些痛点,提出了一种新颖的多模态框架,能够在无需人工标注的情况下自动生成高质量的监督信号。
通过整合 Grounded SAM、LLaVA 和 CLIP,该框架构建了鲁棒的伪分割掩码、描述性标题以及语义对齐的同义词集。模型通过三种专门设计的训练目标进一步优化——包括扩展基础损失(extended grounding loss)、语义一致性损失(semantic consistency loss)和生成式标题重建(generative caption reconstruction),从而在 COCO 数据集上实现了最先进的性能表现。

摘要 (Summary)
本文针对当前开放词汇实例分割(OVIS)和开放集全景分割(OSPS)方法的局限性进行了研究,这些方法通常难以应对带噪的伪掩码、有限的视觉-文本基础对齐,以及处理同义词或词表外(OOV)词汇的困难。
This paper addresses the limitations of current Open-Vocabulary Instance Segmentation (OVIS) and Open-Set Panoptic Segmentation (OSPS) methods, which often struggle with noisy pseudo-masks, limited visual-textual grounding, and difficulties in handling synonyms or out-of-vocabulary (OOV) terms.
作者提出了一种新颖的多模态框架,在无需人工标注的情况下自动生成高质量的监督信号。通过集成 Grounded SAM、LLaVA 和 CLIP,该框架构建了鲁棒的伪分割掩码、描述性标题以及语义对齐的同义词集。模型通过三个专门的训练目标进一步优化——扩展基础损失、语义一致性损失和生成式标题重建,从而在 COCO 数据集上取得了最先进的性能。
The authors propose a novel multimodal framework that automates the generation of high-quality supervision without manual annotation. By integrating Grounded SAM, LLaVA, and CLIP, the framework constructs robust pseudo-segmentation masks, descriptive captions, and semantically aligned synonym sets. The model is further refined through three specialized training objectives—extended grounding loss, semantic consistency loss, and generative caption reconstruction—resulting in state-of-the-art performance on the COCO dataset.
