3D场景理解中的一个重要问题是3D标注的匮乏,所以很多方法都希望利用2D模型强大的能力帮助3D模型提升性能,这篇文章也是如此,这篇文章希望利用2D模型强大的开放词汇分割能力帮助3D模型增强开放词汇下的语义分割能力。话不多说,直接开始看方法。 作者首先列举了目前开放词汇下语义分割的两种SOTA范式,第一种是来自CVPR2023的...
在open vocabulary semantic segmentation领域,一种自然的想法就是提取利用VLM的知识,用VLM的文本特征代替原本的闭集分类器,让分割模型能够识别出novel类别。 5.2 从图像标题数据中学习 除了利用VLM在大规模数据上训练得出的分类性能之外,还有一种广泛存在且易获得的数据类型,即图像标题(image captions)。和预定义好的类别...
We propose a novel method, namely Diff2Scene, which leverages frozen representations from text-image generative models, along with salient-aware and geometric-aware masks, for open-vocabulary 3D semantic segmentation and visual grounding tasks. Diff2Scene gets rid of any labeled 3D data and ...

3.1 Two-stage models for open-vocabulary semantic segmentation 我们的两阶段开放词汇语义分割模型如图所示。它包括一个生成 mask proposals 的分割模型和一个开放的词汇分类模型。 两阶段方法由一个分割模型(如 MaskFormer )和一个 CLIP 模型组成。首先,利用 CLIP 的文本嵌入对改进后的 MaskFormer 进行训练,进行开放...

2.首先训练一个单独的模型生成mask propusals,之后使用CLIP对根据mask裁剪得到的局部图片进行识别。然而,生成mask的模型完全独立于CLIP,生成的mask可能不适合识别,而且会带来较大的计算开销(如Decoupling Zero-Shot Semantic Segmentation,OPEN-VOCABULARY SEMANTIC SEGMENTATION WITH MASK-ADAPTED CLIP等)。
