三维数据的边缘检测

sobel：

	data_nii = sitk.ReadImage(img_path)
    origin = data_nii.GetOrigin()
    spacing = data_nii.GetSpacing()
    direction = data_nii.GetDirection()

    data_float_nii = sitk.Cast(data_nii, sitk.sitkFloat32)

    sobel_op = sitk.SobelEdgeDetectionImageFilter()
    sobel_sitk = sobel_op.Execute(data_float_nii)
    sobel_sitk = sitk.Cast(sobel_sitk, sitk.sitkInt16)

    sobel_sitk.SetOrigin(origin)
    sobel_sitk.SetSpacing(spacing)
    sobel_sitk.SetDirection(direction)
    sitk.WriteImage(sobel_sitk, 'sobel_edge.nii.gz')
