For example , a model incorporating iterative refinement of an initial prototype may be best suited to small - scale trial applications 例如,一个初始样机的模型合并迭代的改进可能最适合小规模的试验性应用。
The method reduces the data to search via decomposing the image to several effectual subimages by the wavelet , then reduces the searching space through multi - resolution analysis , and refine the solution using an iterative refinement algorithm finally 该方法利用小波变换将图像分成若干层次,通过引入有效子图的概念来降低待搜索的数据量,应用小波理论的多分辨分析思想来缩小搜索空间,最后通过迭代求精算法实现了图像的快速、高精度配准。
This thesis discusses the problem free - surface modeling technique of turbine blade according to the property of the runner blade and the present research achievement in free - surface modeling technique , the major study concerned are introduced below : firstly , it accomplished the study of intersection for blade - to - plane and present the method of three - step algorithms such as subdivision > iterative refinements approach ; meanwhile it solved the problem of small area extend of blade by use minimal modulus method 本文针对水轮机叶片的特点,结合曲面造型技术的研究现状,研究了水轮机叶片的nurbs曲线曲面造型问题。主要工作有:第一,完成了叶片与任意平面求交问题的研究,提出分割-迭代-拟合三步求交算法。同时首次应用最小二乘拟合端部法解决了叶片的小区域延展问题。
