例句与用法
- The backward error and the structured backward error of the approximate solution are the criteria to judge the stability and the strong stability of the numerical algorithm . condition number is a measure of the sensitivity to the approximate solution for the perturbation of original date
近似解的最佳向后误差和最佳结构向后误差的数值分别是判别算法的稳定性和强稳定性的标准，而条件数则是反映数值问题的解对于该问题数据扰动的敏感程度。 - In recent years , nonlinear methods have attracted more and more attention and there have been some successful cases , such as median filter , mathematical morphology , etc . as a preferred way to inverstigate nonlinear numerical problems , the continued fractions method can effectively express the gradually changing data or abrupt data , so it is meaningful to study image processing by means of the continued fractions theory and algorithms
近年来在图像处理领域，利用非线性方法进行图像处理取得较好效果的有中值滤波、数学形态学等，非线性方法已引起越来越多研究者的重视。作为研究非线性数值问题的首选方法?连分式方法，不仅能反映数据的渐变性，也能反映数据的突变性。鉴于这些原因，本文将连分式插值和逼近引入到数字图像处理领域，开展了图像插值、图像重建等方面的研究。
