class_docstr: Constructs a PoolFormer feature extractor.
  
  This feature extractor inherits from [`FeatureExtractionMixin`] which contains most of the main methods. Users
  should refer to this superclass for more information regarding those methods.
  
  Args:
      do_resize_and_center_crop (`bool`, *optional*, defaults to `True`):
          Whether to resize the shortest edge of the image and center crop the input to a certain `size`.
      size (`int` or `Tuple(int)`, *optional*, defaults to 224):
          Center crop the input to the given size. If a tuple is provided, it should be (width, height). If only an
          integer is provided, then the input will be center cropped to (size, size). Only has an effect if
          `do_resize_and_center_crop` is set to `True`.
      resample (`int`, *optional*, defaults to `PIL.Image.Resampling.BICUBIC`):
          An optional resampling filter. This can be one of `PIL.Image.Resampling.NEAREST`,
          `PIL.Image.Resampling.BOX`, `PIL.Image.Resampling.BILINEAR`, `PIL.Image.Resampling.HAMMING`,
          `PIL.Image.Resampling.BICUBIC` or `PIL.Image.Resampling.LANCZOS`. Only has an effect if `do_resize` is set
          to `True`.
      crop_pct (`float`, *optional*, defaults to `0.9`):
          The percentage of the image to crop from the center. Only has an effect if `do_resize_and_center_crop` is
          set to `True`.
      do_normalize (`bool`, *optional*, defaults to `True`):
          Whether or not to normalize the input with `image_mean` and `image_std`.
      image_mean (`List[int]`, defaults to `[0.485, 0.456, 0.406]`):
          The sequence of means for each channel, to be used when normalizing images.
      image_std (`List[int]`, defaults to `[0.229, 0.224, 0.225]`):
          The sequence of standard deviations for each channel, to be used when normalizing images.

label_desc: Use image node_id 1 to create a new PoolFormerFeatureExtractor object from inherited base classes: FeatureExtractionMixin, ImageFeatureExtractionMixin with example: obj = PoolFormerFeatureExtractor(do_resize_and_center_crop, size, resample, crop_pct, do_normalize, image_mean, image_std)
