Medial Axis Transformation

The Medial Axis (MA) of an object is the locus of centers of balls which are maximal within the object, together with the limit points of this locus. A ball is maximum within an object if it is contained in the object but is not a proper subset of any other ball contained in the object. The Medial Axis Transform (MAT) is the MA together with the associated radius function that specifies the radius of the maximal ball around any given point on the MA.

Localization

Localization is the process of determining the rigid-body translations and rotations that must be performed on a set of points measured on a manufactured surface to move those points into the closest correspondence with the ideal design surface. In unconstrained localization, all points have equal effect on the determination of the rigid-body transformation, while constrained localization allows a subset of the points to have stronger influence on the transformation.
Abstract is available.

Feature Extraction

During the manufacturing process, a propeller blade surface undergoes slight modifications, that result in small changes to the data describing its features. It is therefore desirable to recompute these features for comparison with the original design data.
Abstract is available.
