LANGUAGE-DRIVEN SEMANTIC SEGMENTATION论文阅读笔记 摘要 文章的主要贡献是提出了一种新的语言驱动的分割模型LSeg,其使用Text encoder编码描述性的输入标签,使用Image encoder计算图像的逐像素的embedding。图像编码器使用的是对比目标训练,目的是将像素的embedding与对应文本标签的embedding进行对齐。text embedding提供了灵活的...
通过矩阵相乘将文本和图像结合起来了。训练时可以学到language aware(语言文本意识)的视觉特征。从而在最后推理的时候能使用文本的prompt任意的得到分割的效果。 本文中文本编码器的参数完全使用的CLIP的文本编码器的参数,因为分割任务的数据集都比较小(10-20万),为保证文本编码器的泛化性,就直接使用并锁住CLIP中文本编...
We present LSeg, a novel model for language-driven semantic image segmentation. LSeg uses a text encoder to compute embeddings of descriptive input labels (e.g., "grass" or "building") together with a transformer-based image encoder that computes dense per-pixel embeddings of the input image....

We conduct extensive experiments on 3D semantic, instance, and panoptic segmentation tasks, covering indoor and outdoor scenes across three datasets. Our method outperforms baseline methods by a significant margin in semantic segmentation (e.g. 34.5%聽鈭悸3%), instance segmentation (e.g. 21.8%聽...
