        Returns:
            [`BatchFeature`]: A [`BatchFeature`] with the following fields:

            - **pixel_values** -- Pixel values to be fed to a model, of shape (batch_size, num_channels, height,
              width).

            - **pixel_mask** -- Pixel masks to be fed to a model, of shape (batch_size, num_pixel_patches).

            - **pixel_values_mixed** -- Pixel values with both postive or negative to be fed to a model, of shape
              (batch_size, num_channels, height, width).

            - **pixel_mask_mixed** -- Pixel masks with both postive or negative to be fed to a model, of shape
              (batch_size, num_pixel_patches).
