WebbWe have two options for converting from SimpleITK to numpy: GetArrayFromImage (): returns a copy of the image data. You can then freely modify the data as it has no effect … Webb4 okt. 2024 · Welcome to SimpleITK! SimpleITK and numpy use a different indexing order. SimpleITK uses x-y-z. Numpy uses z-y-x. The GetImageFromArray method accounts for this. Thus when you inspect the image size afterwards the reported order is x-y-z which matches your original numpy size. With respect to SetSpacing, it should also follow the x …
