A New Model for the Structure of Leaves

This paper proposes a new model for the shapes and details of simple and compound leaves in plants. The layout of leaf is modeled via branching structure generated using B-Splines. The proposed model controls the relationships that govern the shape through the marginal and venation of the considered simple leaf or leaflet. The developed algorithm starts by taking four points that represent the out boundary of a simple leaf or a leaflet of compound one. Then, the algorithm optimizes the value of these parameters in order to get the best representation of the considered leaf/leaflet. The proposed model is tested with acceptable results for various shapes of leaf and compound leaves.
