 The ideal cropped positions are dependent on the specific application you are using the face cropper in.
 Some face embedding extractors work well on loosely cropped faces, while others require the face to be tightly cropped.

+We provide a few reasonable defaults that are used in our implemented baselines. They are accessible through an utilitary function as follows :

   It is typically use with a 5:4 aspect ratio for the :code:`cropped_image_size`

 We present hereafter a visual example of those crops for the `eyes-center` annotation type.
