Function resize_center

monai/transforms/utils.py:340–358

Resize `img` by cropping or expanding the image from the center. The `resize_dims` values are the output dimensions (or None to use original dimension of `img`). If a dimension is smaller than that of `img` then the result will be cropped and if larger padded with zeros, in both cases t
