A Parametric Active Polygon for Leaf Segmentation and Shape Estimation

Abstract : The identication of tree leaves from photographs taken in a natural environment is a di cult task where the quality of the seg- mentation is of primary importance. In this paper we present a system that combines a rst, unre ned segmentation step, with an estimation of descriptors depicting the general shape of a simple leaf. It is based on a light polygonal model, built to represent most of the leaf shapes, that will be deformed to t the leaf in the image. Avoiding some classic obstacles of active contour models, this approach gives promising results, even on complex natural photographs, and constitutes a solid basis for a leaf recognition process.
