Curve and Fuzzy Curve Pyramids

The curve pyramid where linear structures of images are represented by curve relations is shown. The basic steps for deriving a lower resolution representation of the curve pyramid and the properties of the 2x2/2 curve pyramid are described. As example, the 2x2/2 curve pyramid is used to remove short edge features of an edge image of archeological findings. Furthermore, the fuzzy curve pyramid as an extension of binary curve pyramids to curves with strenghts is demonstrated. Again, the basic steps for deriving a lower resolution representation and the properties are described. The fuzzy curve pyramid is applied to the same data of an edge image of archeological findings as the curve pyramid.
