| 摘 要： | 从多项式逼近的思想出发，利用遗传算法在多项式系数构成的高维空间中依据表征象点均匀分布程序的均匀分布了池数搜索全局最优的一组多项多系数，并用与之相应的多项式来逼近未知的逆变形函数，从而达到无导师几何校正的目的。

| Abstract: | In this paper, a new unsupervised geometric correction approach based on polynomial approximation was presented. Uniform Distribution (UD) function is defined to show the degree of image distortion. Genetic algorithm is used to search the coefficients of the polynomials which are used to approximate the reverse transformation function of the distorted image. The best polynomials then will be used to correct the distortion. |
