Inexact graph matching for fingerprint classification

Lumini A., Maio D., Maltoni D.

Machine Graphics and Vision

1999

Vol. 8, No. 2

231-248

In this work we introduce a new structural approach to automatic fingerprint classification. The fingerprint directional image is partitioned into "homogeneous" connected regions according to the fingerprint topology. A relational graph is constructed in order to compactly summarize the fingerprint macro-structure resulting from the partitioning process. An inexact graph matching technique is adopted to compare this graph with a set of prototype graphs which have been a-priori derived starting from a well-known classification scheme.

Image generation by Petri nets

Lumini A., Maio D.

Machine Graphics and Vision

1998

Vol. 7, No. 1/2

221-232

This paper presents a new approach to computer image generation. The basic idea is to translate the evolution of a Petri net into a graphic output. In particular, we focus on three methods for image generation which exhibit a certain analogy whit fractals. Some experimental results are reported together whit a brief investigation on the relationships between generated images and thier corresponding Petri nets.
