# Module `facetorch.analyzer.unifier.core`

## Classes

`class FaceUnifier (transform: torchvision.transforms.transforms.Compose, device: torch.device, optimize_transform: bool)`

  FaceUnifier is a transform based processor that can unify sizes of all faces and normalize them between 0 and 1.

  ## Args

  `transform` :`Compose`
    Composed Torch transform object.
  `device` :`torch.device`
    Torch device cpu or cuda object.
  `optimize_transform` :`bool`
    Whether to optimize the transform.
