This paper introduces a method of recognizing leaf images based on shape features.Firstly,we apply image pre-processing techniques to get the contours of the leaves.Then we extract eight geometric features including rectangularity,circularity,eccentricity,etc,and seven moment invariants from leaves' contours for classification.Finally we propose a new moving menter hypersphere classifier to address these shape features.As a result there are more than 20 kinds of plant leaves successfully recognized.The aver...
