摘要:

我们推出了一个包含6096张高分辨率航拍图像的独特语义分割数据集,这些图像拍摄了澳大利亚新南威尔士州贝加山谷的本地草种和入侵草种,旨在解决计算机视觉领域中生态数据占比不足的问题。由于草种的重叠与分布特性,该数据集带来了极具挑战性的任务,这对推动生态和农学应用中的模型发展至关重要。本研究提出一种基于同伦的多目标微调方法,该方法可平衡分割精度与上下文一致性,适用于多种模型。通过将用于像素级分类的DiceCELoss与用于空间连贯性的平滑损失相结合,该方法在训练过程中不断演进,以增强对噪声数据的鲁棒性。我们通过在Segment Anything Model(SAM,分割一切模型)上开展案例研究建立了性能基线,证明了该方法的有效性。我们的标注方法论重点关注笔刷大小、缩放控制和内存管理,确保了高质量数据集的构建。该数据集和代码将公开发布,旨在推动计算机视觉、机器学习和生态学研究的发展,助力环境监测与可持续发展。

英文摘要:

We introduce a unique semantic segmentation dataset of 6,096 high-resolution aerial images capturing indigenous and invasive grass species in Bega Valley, New South Wales, Australia, designed to address the underrepresented domain of ecological data in the computer vision community. This dataset presents a challenging task due to the overlap and distribution of grass species, which is critical for advancing models in ecological and agronomical applications. Our study features a homotopy-based multi-objective fine-tuning approach that balances segmentation accuracy and contextual consistency, applicable to various models. By integrating DiceCELoss for pixel-wise classification and a smoothness loss for spatial coherence, this method evolves during training to enhance robustness against noisy data. Performance baselines are established through a case study on the Segment Anything Model (SAM), demonstrating its effectiveness. Our annotation methodology, emphasizing pen size, zoom control, and memory management, ensures high-quality dataset creation. The dataset and code will be made publicly available, aiming to drive research in computer vision, machine learning, and ecological studies, advancing environmental monitoring and sustainable development.
