AI总结:

本文评估了 SAM、SAM 2、SAM 2.1 及 CNN 在不同光照和分辨率下分割航拍太阳能电池板的性能,发现用户框提示和 YOLOv9 自动提示能显著提升 SAM 系列模型表现,而 Eff-UNet 在高分辨率自动分割中更具实用性。

摘要:

本文深入分析了零样本、基于提示的 Segment Anything Model(SAM)及其更新版本 SAM 2 和 SAM 2.1,以及不可提示的传统卷积神经网络(CNN)在 RGB 航空遥感影像中分割太阳能电池板的有效性。研究在不同光照条件、空间分辨率和提示策略下对这些模型进行了评估。SAM 2 相较于 SAM 略有改进,而 SAM 2.1 则表现出显著改进,尤其是在次优光照和低分辨率条件下。当使用用户定义的边界框进行提示时,SAM 模型在所有场景下均优于 CNN;特别是,研究发现用户框提示对于在低分辨率数据中取得合理性能至关重要。此外,在高分辨率下,YOLOv9 自动提示通过为 SAM 提供可靠提示,优于用户点提示。在低分辨率下,由用户点提示的 SAM 2.1 表现出与由 YOLOv9 提示的 SAM 2.1 相似的性能,突显了其单击零样本改进能力。在具有最优光照的高分辨率影像中,Eff-UNet 优于由 YOLOv9 提示的 SAM 模型,而在次优光照条件下,Eff-UNet 与由 YOLOv9 提示的 SAM 2.1 性能相近。然而,SAM 的资源消耗更大,尽管 SAM 2.1 的推理时间有所改善,Eff-UNet 仍更适合高分辨率数据中的自动分割。本研究详细说明了各模型的优势与局限性,并概述了用户提示图像分割模型的鲁棒性。

英文摘要:

This paper provides insights on the effectiveness of the zero shot, prompt-based Segment Anything Model (SAM) and its updated versions, SAM 2 and SAM 2.1, along with the non-promptable conventional neural network (CNN), for segmenting solar panels in RGB aerial remote sensing imagery. The study evaluates these models across diverse lighting conditions, spatial resolutions, and prompt strategies. SAM 2 showed slight improvements over SAM, while SAM 2.1 demonstrated notable improvements, particularly in sub-optimal lighting and low resolution conditions. SAM models, when prompted by user-defined boxes, outperformed CNN in all scenarios; in particular, user-box prompts were found crucial for achieving reasonable performance in low resolution data. Additionally, under high resolution, YOLOv9 automatic prompting outperformed user-points prompting by providing reliable prompts to SAM. Under low resolution, SAM 2.1 prompted by user points showed similar performance to SAM 2.1 prompted by YOLOv9, highlighting its zero shot improvements with a single click. In high resolution with optimal lighting imagery, Eff-UNet outperformed SAMs prompted by YOLOv9, while under sub-optimal lighting conditions, Eff-UNet, and SAM 2.1 prompted by YOLOv9, had similar performance. However, SAM is more resource-intensive, and despite improved inference time of SAM 2.1, Eff-UNet is more suitable for automatic segmentation in high resolution data. This research details strengths and limitations of each model and outlines the robustness of user-prompted image segmentation models.
