Webb7 mars 2024 · 这行代码的意思是将一个 NumPy 数组转换为 SimpleITK 图像对象。其中,image 是一个 NumPy 数组,astype(np.float32) 是将数组中的元素类型转换为 float32 类型。而 sitk 是 SimpleITK 库的别名,GetImageFromArray 是 SimpleITK 库中的一个函数,用于将 NumPy 数组转换为 SimpleITK 图像对象。 Webb2 mars 2024 · Below is a simple example which creates a binary mask via thresholding and zeros out all the voxels that are in the background. import SimpleITK as sitk image = sitk.ReadImage ('training_001_ct.mha') foreground_mask = image>0 foreground_image = image*sitk.Cast (foreground_mask, image.GetPixelID ()) 1 Like
WebbAs the SimpleITK rotation parameterization uses the vector portion of a versor we don't have an intuitive way of specifying rotations. We therefor use the ZYX Euler angle parametrization and convert to versor. Webb模糊操作(例如,高斯模糊)是线性的,从数学上讲模糊过程是可逆的,即可以通过模糊图像恢复原始高清图像。但在实践中,该问题的逆过程计算起来非常困难。在本节中,我们学习了如何通过对图像的拉普拉斯方差进行简单的阈值处理来检测图像是否模糊,以及如何使用 SimpleItk 和 scikit-image 库函数 ...
WebbWe will use two approaches: Segment the fiducial using a thresholding approach, derive the sphere's radius from the segmentation. This approach is solely based on SimpleITK. Localize the fiducial's edges using the Canny edge detector and then fit a sphere to these edges using a least squares approach. http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/Python_html/70_Data_Augmentation.html
