(SRI) Together, these papers use a
class of objective functions to order labels and maximize the probability of
correct division. It combines geometry (rectangles) and image data
(uniformity) to fit the shape to the data.

of the segmentation. Applied to buildings, roads, and trees.
Pieces of the boundary are used to estimate locations for other
pieces.

*Segmentation, Edges*. (SRI) Improve the segmentations by using straight line sides of
regions as constraints. The regions are found by an Ohlander-type
segmentor and refined by finding straight lines as sides and
looking at the arrangement of the straight lines.
