Axis estimation and grouping of rotationally symmetric object segments

作者：

Highlights：

• The symmetric axis of a pottery is estimated from its small fragment.

• The curvature is computed from the intersection of hypothetical plane and sherd.

• Sherds can be grouped via their surface principal curvature histogram.

• Grouping can divide the problem into small set of the problem.
