Superpixel Label: Sporting and Athletic Fields
Sporting fields and other athletic areas should be treated like other outdoor scenes, except for ONE important difference:
Grass and grasslike turf on a playing field should be labeled: Ground - Playingfield Turf.
So on a baseball field, label the grass as Ground - Playingfield Turf, and label the dirt as Ground Dirt. Skate parks can be Ground Other or Pavement.
Stadium seats are not furniture.
