Abstract

In this paper, a method for recognizing plant species by the shapes of leaves of plants is presented. The recognition is based on a hierarchical representation of shape features. First, the structures of the shapes of leaves are analyzed and the shapes of components are extracted in detail. The structures and detailed shapes of leaves are approximated by polygons whose vertices are critical points of curvature of contours of leaves. The method takes variations of shapes of leaves of the same species into account also. Experimental results using a number of species in the family of Acer (Maple) indicate that structures of leaves and shapes of their components can be considered as landmarks to recognize the species of plants.
