摘要:

最近,分割一切模型(SAM)在各种实例分割任务中展现出强大的泛化能力。然而,其性能严重依赖于手动提示的质量。此外,实例分割方法通常使用的RGB图像本质上缺乏深度信息。因此,这些方法感知空间结构和描绘物体边界的能力受到阻碍。为了解决这些挑战,我们提出了一种用于实例分割的自提示深度感知SAM(SPDA-SAM)。具体来说,我们设计了一个语义-空间自提示模块(SSSPM),该模块分别从SAM的图像编码器和掩码解码器中提取语义和空间提示。此外,我们引入了一个粗到细的RGB-D融合模块(C2FFM),其中从单目RGB图像中提取的特征与从中估计的深度图进行融合。特别地,深度图中的结构信息用于为特征融合提供粗粒度指导,而深度的局部变化被编码以融合细粒度特征表示。据我们所知,SAM尚未以这种自提示和深度感知的方式进行探索。实验结果表明,我们的SPDA-SAM在十二个不同的数据集上优于最先进的对应方法。这些令人鼓舞的结果应归因于自提示的引导以及粗到细RGB-D融合操作对空间信息损失的补偿。

英文摘要:

Recently, Segment Anything Model (SAM) has demonstrated strong generalizability in various instance segmentation tasks. However, its performance is severely dependent on the quality of manual prompts. In addition, the RGB images that instance segmentation methods normally use inherently lack depth information. As a result, the ability of these methods to perceive spatial structures and delineate object boundaries is hindered. To address these challenges, we propose a Self-prompted Depth-Aware SAM (SPDA-SAM) for instance segmentation. Specifically, we design a Semantic-Spatial Self-prompt Module (SSSPM) which extracts the semantic and spatial prompts from the image encoder and the mask decoder of SAM, respectively. Furthermore, we introduce a Coarse-to-Fine RGB-D Fusion Module (C2FFM), in which the features extracted from a monocular RGB image and the depth map estimated from it are fused. In particular, the structural information in the depth map is used to provide coarse-grained guidance to feature fusion, while local variations in depth are encoded in order to fuse fine-grained feature representations. To our knowledge, SAM has not been explored in such self-prompted and depth-aware manners. Experimental results demonstrate that our SPDA-SAM outperforms its state-of-the-art counterparts across twelve different data sets. These promising results should be due to the guidance of the self-prompts and the compensation for the spatial information loss by the coarse-to-fine RGB-D fusion operation.
