Abstract – Pattern recognition problems computer based are very important and
essential in our real life. There are many approaches have been used in pattern
recognition problem such as: Fourier Descriptor, Moment Invariant. But the main defect
of these methods is the long time processing and large computer space. This paper,
presents a new approach Artificial Intelligence, of Rule Induction technique. By this
approach, the essential and specific features of object have been extracted from contour
of object to be recognized. The characteristic of these features are easy computed and
requires fewer amounts of time and space, then high speed in recognition and decision.
Such features are (number of curves inside the fingerprint, number of check point for
each curve). It gives good and accurate results. We test the performance of this system
using many contours of fingerprint, and get good and accurate results.
