Recognition of plant leaf image based on fractal dimension features

This work proposed a new method of describing the characteristics of plant leaves based on the outline fractal dimension and venation fractal dimension. First, using multiple threshold edge detection method to separate leaf edge and vein, and get multiple veins. Then, the two-dimensional fractal dimension of the leaf edge image and multiple vein images will be calculated, and a new ring projection wavelet fractal feature for leaf shape is also adopted. Finally, these two kinds’ fractal dimension features are used to plant leaves classification and recognition. The experimental results demonstrated the effectiveness of the fractal dimension feature method.
