Visual basic has been used to interpolate points on the front and the rear b - splines ; compare the sample data with the original data of fan 利用b樣條曲線插值運(yùn)算計(jì)算葉片引導(dǎo)線上點(diǎn)的數(shù)據(jù),并與原始的cad模型進(jìn)行比較以確定預(yù)補(bǔ)償模型的變形大小。
On the basis of summarizing current fractal dimension algorithms , the random midpoint replacement algorithm was employed to obtain interpolating point according to the fractal features of remote sensing image , so the current widely used triangular prism method was improved 摘要在總結(jié)現(xiàn)有分形維數(shù)計(jì)算方法的基礎(chǔ)上,根據(jù)遙感影像的分形特性,利用隨機(jī)中點(diǎn)替代法獲取插值點(diǎn),從而對(duì)目前普遍使用的三棱柱面法進(jìn)行了改進(jìn)。
With the review of digital image properties and continued fractions theory , this dissertation focuses on the study of the image interpolation and image reconstruction ; the main contributions are as fallows : first of all , the methods of solving the problem of inverse difference being infinite are successfully found while constructing the thiele - type continued fractions . in this case it is proposed to reorder the set of interpolating points and then construct a thiele - newton blending continued fraction 本文的主要工作可歸納如下:首先,在以圖像像素為插值節(jié)點(diǎn)集,構(gòu)造連分式插值函數(shù)過(guò)程中出現(xiàn)逆差商為無(wú)窮大的情況,給出了合理的解決辦法,提出了重新調(diào)整插值節(jié)點(diǎn)集的節(jié)點(diǎn)順序、構(gòu)造thiele - newton型混合有理的插值方法。
