                         ecology, but the manual process is cumbersome even for 
                         experimented taxonomists. Technological advances allows the 
                         development of strategies to make these tasks easily and faster. 
                         In this context, this paper describes a methodology for plant 
                         identification and classification based on leaf shapes, that 
                         explores the discriminative power of the contour-centroid distance 
                         in the Fourier frequency domain in which some invariance (e.g. 
                         rotation and scale) are guaranteed. In addition, it is also 
                         investigated the influence of feature selection techniques 
                         regarding classification accuracy. Our results show that by 
                         combining a set of features vectors - in the principal components 
                         space - and a feedforward neural network, an accuracy of 97.45% 
                         was achieved.",
