  Args:
      img_rgb: a tensor or numpy array of shape (H, W, C), where H and W correspond to
          the height and width of the image respectively. C is the number of
          color channels. The image is required to be in RGB format since that
          is a requirement of the Matplotlib library. The image is also expected
          to be in the range [0, 255].
      meta (MetadataCatalog): image metadata.
