Paddy is one of major crops grown in China. Fractal dimension is an important parameter used to describe geometrical characteristics of many natural objects. The objective of this study is to investigate mathematical relationships between the fractal dimension and the yield of the paddy spike based on the fractal theory and the image processing technologies. The color images of paddy spikes were taken with a digital camera, then they were transacted to the gray using image processing. Fractal dimensions of the spikes were computed using the Box-Counting Method based on the gray images. The results indicate that there is a significant linear relationship between the fractal dimension and the yield.
