an be overridden by the `image_mean` parameter in the `preprocess` method.
        image_std (`float` or `List[float]`, *optional*, defaults to `IMAGENET_STANDARD_STD`):
            The standard deviation to use if normalizing the image. This is a float or list of floats of length of the
            number of channels of the image. Can be overridden by the `image_std` parameter in the `preprocess` method.
        do_reduce_labels (`bool`, *optional*, defaults to `False`):
            Whether or not to reduce all label values of segmentation maps by 1. Usually used for datasets where 0 is
            used for background, and background itself is not included in all classes of a dataset (e.g. ADE20k). The
            background label will be replaced by 255. Can be overridden by the `do_reduce_labels` parameter in the
            `preprocess` method.
