This shpae of fruit is one of the most important features in classification. Various mathematical methods for describing the shape of irregular fruits were investigated. It was not suitable to adopt curve fitting to describe the pear shape in the course of fruit classification. The new method to calulate centroid coordinates and to describe the shape of the object only based on the boundary information was put forward. It was greatly efficient to describe the shape using Fourier descriptor, which uses boundary radius and its Fourier transform to spectrum domain. It appeared that the change patterns of first 4 harmonics were sufficient for representing the main shape features of fruit, and more accuracy in the reconstruction, especially at the calyx pole, was obtained with first 15 harmonics. Besides, they allow the reconstruction of the pear shape. Furthermore, the Fourier descriptors can made in variant to translation, rotation, and scale, this feature is very important for "on-line" grading objectives. It was found that the identification accuracy reached 90% by applying the Fourier descriptor in combination with artificial neural networks. This method also could be used to identify the shape of other fruits if suitable training set is found.

水果的形状是水果分级的重要指标之一.本文研究了不规则物体形状的数学描述方法,认为在水果的分级过程中采用曲线拟合的方法来描述水果的形状是不合适的;提出了仅需利用物体的边界信息求物体的形心坐标和描述果形的新方法;发现用Fourier描述子的前4个谐波分量的变化特性就能较好地代表水果的形状,用前15个谐波分量来描述形状则可以达到相当高的精度.而且傅立叶描述子可以进行平移、旋转和缩放,并具有很强的水果外形重建功能,是一描述水果形状的非常有效的算法.

In this paper, the state-of-arts of applications of fractal theory to roughness-exterior expressing, the calefactive distributing of friction , the forecast model of wear and tear, fault diagnosis , soil-cultivating and the fruit classification by computer vision are reviewed. [
