pyiqa.archs.constants
=====================

.. py:module:: pyiqa.archs.constants

.. autoapi-nested-parse::

   Shared normalization constants for architecture backbones.

   This module centralizes channel-wise mean and standard deviation values used by
   models in :mod:`pyiqa.archs` for preprocessing input images.

   All tuples follow RGB channel order.
