APPLICATIONS OF WATERLINING: MEDIAL-AXIS TRANSFORMATION and SHAPE RECONSTRUCTION
The medial-axis of a shape, also known as centerline, midline, skeleton and axis-of-symmetry, is a structure much used in Pattern Recognition as an abstracter of shapes. The medial-axis can also be used to reconstruct the original shape.
The procedure that yields the medial-axis of a shape is called the medial-axis transformation or MAT. Several approaches to that transformation have been proposed and implemented. The one illustrated here consists of first waterlining the shape and then threading the medial-axis through particular waterline points. This application is used in almost all the solutions we inform in our site. For more on reconstructions see next PAGE.
