I want to transform the following code into ITK(c++ version), But I do not know which functions could do it. HELP!

```auto
for c in labels: # labels is list that stores the labelmap's unique value
      mask = segmentation==c #segmentation is LabelMap
      reshape_multihot = resize(mask,shape.....) # resize import from skimage.transform
      reshape[reshape_multihot>=0.5]=c

```

Hi,

The following may be useful:

- [itk::MaskImageFilter](https://itk.org/Doxygen/html/classitk_1_1MaskImageFilter.html)
- [itk::ResampleImageFilter](https://itk.org/Doxygen/html/classitk_1_1ResampleImageFilter.html)
