images with ground truth 这句话该怎么翻译

摘自维基：“In machine learning, the term "ground truth" refers to the accuracy of the training set's classification for supervised learning techniques. This is used instatistical models to prove or disprove research hypotheses. The verb "ground truthing" refers to the process of gathering the proper objective data for this test.”

——我也经常在图像处理论文里看到这个词，一般会在图像和机器学习的交叉领域出现，简单来说就是训练集图片中被确定出的“理想、正确的”目标。

是在有监督学习中的，是指数据集有正确的标注

ground truth refer to a process in which a pixel on a satellite image is compared to what is there in reality (at the present time) in order to verify the contents of the pixel on the image.就理解为图像真实的像素点啦
