在农学、医学、遗传学、生态学和分类学等各个研究领域中，经常需要对生物器官的形状进行定量评估。由Kuhl和Giardina(1982)提出的椭圆傅立叶描述符(EFDS)可以描述任何类型的具有封闭的二维轮廓的形状，并且已经被有效地应用于动物各种生物形状的评估(Bierbaum和Ferson 1986；Diaz等人)。1989年；Ferson et al.1985；Rohlf和Archie 1984)和植物(Furuta等人)。1995年；岩田等人。1998年；McLellan 1993；Ohsawa等人。1998年；怀特等人。(1988年)。在数量遗传学中，形态量化是评价形态性状遗传的先决条件。有许多报告表明，基于EFDS的测量有助于对植物和动物器官的形状进行量化。例如，岩田等人(2000)对日本萝卜(Raphanus sativus L.)的形状进行了双等位基因分析。根，用EFDS的主成分得分作为形状特征。还利用EFDS的主成分分数对果蝇种雄性生殖器的形状进行了数量性状基因座(QTL)分析(Laurie et al.1997；Liu et al.1996年)。基于EFDS的形状评价方法可以成为分析生物形状的有力工具，但由于涉及到图像处理、轮廓记录、描述符的推导以及描述符的多变量分析等复杂的过程，因此研究人员使用该方法并不容易。
Quantitative evaluation of the shapes of biological organs is often required in various research fields, such as agronomy, medicine, genetics, ecology, and taxonomy. Elliptic Fourier descriptors (EFDs), proposed by Kuhl and Giardina (1982), can delineate any type of shape with a closed two-dimensional contour and have been effectively applied to the evaluation of various biological shapes in animals (Bierbaum and Ferson 1986; Diaz et al. 1989; Ferson et al. 1985; Rohlf and Archie 1984) and plants (Furuta et al. 1995; Iwata et al. 1998; McLellan 1993; Ohsawa et al. 1998; White et al. 1988). Quantization of shapes is a prerequisite for evaluating the inheritance of morphological traits in quantitative genetics. There are many reports showing that measurements based on EFDs are helpful for such quantization of the shapes of plant and animal organs. For instance, Iwata et al.(2000) conducted a diallele analysis of the shape of Japanese radish (Raphanus sativus L.) roots, using the principal component scores of the EFDs as shape characteristics. Quantitative trait loci (QTL) analysis has also been conducted using the principal component scores of EFDs concerning the shape of the male genitalia of Drosophila species (Laurie et al. 1997; Liu et al. 1996). The shape evaluation method based on EFDs can be a powerful tool for analyzing biological shapes, but it is not easy for a researcher to use this method because it involves several complex procedures, such as image processing, contour recording, derivation of the descriptors, and multivariate analysis of the descriptors.
