Ground truth refers to the accurate and objective information or data that is used as a reference point to evaluate or verify the accuracy of other information or data. In various fields, such as remote sensing, machine learning, and computer vision, ground truth data is often used to train algorithms or models and to assess their accuracy. Ground truth can be obtained through direct measurements, observations, or expert knowledge, and it provides a reliable benchmark for evaluating the performance of automated systems or models.

在机器学习和计算机视觉等领域,ground truth指的是真实的、正确的或最佳的结果,作为对比模型的预测或分类结果的参考。例如,在图像分类任务中,ground truth可能是人工标注的正确的图像类别,而模型的输出是预测的图像类别。在这种情况下,我们可以通过计算模型的准确率来评估模型的性能,也就是模型预测的图像类别与ground truth之间的差异。

"ground truth" 图通常是指在机器学习中用于评估模型性能的标准数据集或标签集。在训练和测试机器学习模型时,通常需要一个标准数据集或标签集作为参考,以帮助评估模型的预测准确性。这个标准数据集或标签集就被称为"ground truth"。 "ground truth" 图可以用来训练深度学习模型,例如图像分割任务中,每个像素都必须被分到正确的物体或背景中,这就需要有一个准确的"ground truth" 图来进行训练和测试。
