我正在python(Windows)中的.nii文件中执行N4偏差校正。为此,我正在使用SimpleITK。在输入图像时,在读取文件时遇到了问题。
代码:
print("N4 bias correction runs.")
inputImage =sitk.ReadImage("C/Users/LENOVO/Desktop/Brats18_2013_1_1_t1.nii")
maskImage = sitk.OtsuThreshold(inputImage,0,1,200)
sitk.WriteImage(maskImage,"C/Users/LENOVO/Desktop/Brats18_2013_1_1_t1_Mask.nii")
inputImage = sitk.Cast(inputImage,sitk.sitkFloat32)
corrector = sitk.N4BiasFieldCorrectionImageFilter();
output = corrector.Execute(inputImage,maskImage)
sitk.WriteImage(output,"C/Users/LENOVO/Desktop/Brats18_2013_1_1_t1_Mask.nii")
print("Finished N4 Bias Field Correction.....")
错误:

答案 0 :(得分:0)
如果要使用Unix样式的路径,则需要一个斜杠,因此文件路径应为: “ /C/Users/LENOVO/Desktop/Brats18_2013_1_1_t1.nii /”
或者您可以使用Windows样式的路径,那么它将是: “ c:\ Users \ LENOVO \ Desktop \ Brats18_2013_1_1_t1.nii”
