orthogonal polynomial method meaning in English

正交多项式方法

A discrete orthogonal polynomial method is put forward for curve fitting sub - pixel edge detection algorithm , which decomposes two - dimensional curve fitting into one - dimensional curve fitting , and improves the reliability and computation speed of the algorithms
引入离散正交多项式，提出了一种新的曲面拟合亚像素边缘检测算法。该算法将二维曲面拟合分解为一维曲线拟合，大大提高了算法的可靠性和速度。
( 3 ) compare the complexity and precision of the polynomial method and orthogonal polynomials method used in geometrical adjustment , an experiment is made ; some surface fitting method used in spatial co - registration of multiresolution image are studied and experiments are made to show their different in effects ; in order to increase the spectral inherit , we make a histogram match in images to be fused
比较了图像几何校正的多项式方法和正交多项式方法在复杂度与精度上的差异，进行了仿真实验；研究了不同插值技术在图像配准中的应用，对不同插值方法的效果进行了比较，给出了示意图；为消除图像灰度级不匹配对融合结果的影响，对待融合图像的灰度直方图进行了匹配处理。
