之前程序使用的是PIL(Python image library),今天遇到了另一种图像处理包--skimage。 skimage即scikit-image,PIL和Pillow只提供最基础的数字图像处理,功能有限,OpenCV是一个c++库,只是提供了Python接口,更新速度非常慢,scikit-image是基于scipy的一款图像处理包,将图片作为numpy数组进行

我们为您做的是从第 10-12 章的LunaDataset中复制候选列表,并从第十三章的Luna2dSegmentationDataset中将其分割为测试和验证数据集。由于这是非常机械的,并且没有太多细节可供学习(您现在已经是数据集专家了),我们不会详细展示代码。 我们将通过重新运行分类器的训练来重新训练我们的分类模型:¹ ...
我们将在以下部分详细介绍segmentCt、groupSegmentationOutput和classifyCandidates方法。 14.3.1 分割 首先,我们将对整个 CT 扫描的每个切片执行分割。由于我们需要逐个患者的 CT 逐个切片进行处理,我们构建一个Dataset,加载具有单个series_uid的 CT 并返回每个切片,每次调用__getitem__。
