initial estimate造句
例句与造句
- Abstract : the nr - bp methed was wsed for the si mulated calculation of cryogenic purifier distillation . the results of calculatio n showed that this method possessed the advantages of low initial estimate value s ， rapid and steady convergence and so on , and were in good agreement with the d es ign values of referance
文摘:采用新松弛法( nr )与泡点法( bp )结合对深冷净化精馏塔进行了模拟计算.计算结果表明，该法具有初值要求不高、收敛稳定、收敛速度快等优点，并与文献设计值吻合很好 - The new algorithm starts from an initial estimate which is based on the hough transform , and a rectangular window is centered using the current line approximation , and a new line estimation is generated by making a total least squares fit through the pixels contained within the window . this is repeated until convergence is reached . lastly , we have suggested a new technique which may recover the motion and structure parameters of a moving object by using of 21 optical flow lines based on the optical flow fields of the feature line this thesis is the project supported by aeronautical foundation science ( no . 99f53065 ) and research center of measuring and testing technologies , and control engineering in nanchang institute of aeronautical technology ( no . 2001 - 15 )
算法的思路是：首先，在小区域内运用霍夫变换确定直线的初始值；其次，以直线的初始值所对应的直线为中心线，建立一个矩形框；最后，利用矩形框内所包含的边缘点数据不断地迭代直至收敛，从而达到进一步修正直线的坐标参数；本文基于特征直线的光流场，即线流场，建立了一种利用21条光流线确定空间三维物体旋转运动参数、平移运动参数以及对应的空间直线坐标的线性算法。 - It's difficult to find initial estimate in a sentence. 用initial estimate造句挺难的
