Ground truth orientation map for the UCB room dataset.

For each image, each pixel was labeled as
FLOOR, CEILING, LEFT WALL, RIGHT WALL, MIDDLE WALL

We labeled the room images as if there were no clutter
in the way (i.e. as if the walls were completely visible,
and not occluded by objects in the way).

We provide two different formats.

.tif format (useful for visualizing)
Conventions:
White pixel RGB=(255,255,255) -> FLOOR
Yellow pixel RGB=(255, 255, 0)-> MIDDLE WALL
Blue pixel RGB=(0, 0, 255)-> RIGHT WALL
Red pixel RGB=(255, 0, 0) -> LEFT WALL
Green pixel RGB=(0, 255, 0)-> CEILING

.mat format (matlab matrices)
Conventions:
1 -> FLOOR
2 -> MIDDLE WALL
3 -> RIGHT WALL
4 -> LEFT WALL
5 -> CEILING
