Normalize          Determine whether to use normalization in preprocessing of image or not.                                                                                                                                                                                      
Normalize_ROI      If a mask is supplied and this is set to True, normalize image based on supplied ROI. Otherwise, the full image is used for normalization using the SimpleITK Normalize function. Lastly, setting this to False will result in no normalization being applied.
ROIDetermine       Choose whether a ROI for normalization is provided, or Otsu thresholding is used to determine one.                                                                                                                                                            
ROIdilate          Determine whether the ROI has to be dilated with a disc element or not.                                                                                                                                                                                       
ROIdilateradius    Radius of disc element to be used in ROI dilation.                                                                                                                                                                                                            
Method             Method used for normalization if ROI is supplied. Currently, z-scoring or using the minimum and median of the ROI can be used.                                                                                                                                
Resampling         Determine whether the image and mask will be resampled or not.                                                                                                                                                                                                
Resampling_spacing Spacing to resample image and mask to, if resampling is used.
