In a previous work, we defined a new approach to evaluating directional
relations between objects (such as "to the right of", "above"...). The
approach is based on the computation of a histogram of forces. We show
in the present paper that the notion of the histogram of forces can
also be useful in pattern recognition. The aim of this study is to
classify orbits and sinuses. Using force histograms instead of
geometrical criteria (like compactness or degree of ellipticity) allows
more accurate classification to be produced. Moreover, the proposed
approach is low computing time.
