对的,simulation的时候要用CAVE 512×512,切出256×256的patch训练。real 训练的时候要用 CAVE 1024×1024,切出660×660的patch训练。在data prepare那里都有提供这两个数据集的下载链接。

谢谢你的评论解决了我的困惑。尽管如此,我在随后的复现工作中又遇到了新的困难。我已经仔细查看了作者在真实实验中的可用代码,其中图像尺寸被裁切为了384,并且cave数据集中只取了30张图。我想知道代码中的默认设置是否不适合于660660的图像,或许我应该尝试将cave的图像选择由默认的30张更改为1024版本的205张?此外,如果是针对384384的图像所设计的代码,应该如何将观测图像采样至适合维度?

我们训练的时候将图像裁成384是为了节省计算量。你可以完全采用我们的默认设定。训练张数就用30张即可。
当然你可以试一下把训练张数扩大到205张,只是那样比较费时间。

对您的耐心表示感谢。我们试图采用您所推荐的第一种方法,即,将图像裁切至384,对模型进行训练。然而,这将导致一个问题,我需要在测试时对真实获取的观测图像进行裁切。换句话讲,我需要将660x714尺寸的观测图像裁切至384x438。我的疑惑在于,在使用真实观测图像进行测试时,裁切操作只是torch中的数组行列选取还是对整张图像进行指定步长采样操作?或者在测试时有其他方法可以通过尺寸为384训练的模型对660的观测进行直接重建?

测试的时候不用裁剪,直接用660×660测。你可以看看我们的real测试代码
