 Note on the determination of the best-fitting plane for a given set of directions First, the surface normal on every point is estimated by the least squares best fitting plane method. While adding elements the parameters of the fitting plane are updated accordingly. We use a least squares fitting plane as the parametric domain plane. The relative translational orientation of each helix is based upon forming the best fitting plane of all the hydrophobic centers obtained from step 2. 更多 In this paper, the problem of finding the intersection of two parametric surfaces is discussed, by using the subdivision technique based on the idea of piecewise linear approximation and its error estimation, and a subdivision method that can determine the number of times of subdivision in advance according to the demanded precision is proposed, which uses the arbitrary triangular piecewise linear approximation to avoid replacing each original sub-surface by the fitting plane of its four vertices and guarantees... In this paper, the problem of finding the intersection of two parametric surfaces is discussed, by using the subdivision technique based on the idea of piecewise linear approximation and its error estimation, and a subdivision method that can determine the number of times of subdivision in advance according to the demanded precision is proposed, which uses the arbitrary triangular piecewise linear approximation to avoid replacing each original sub-surface by the fitting plane of its four vertices and guarantees global continuity of the piecewise linear approximating surface. So the intersection line obtained by this method is better than that got by the rectangular subdivision method in the effect of approximation and fairing. Furthermore, this method is suitable for all continuously differentiable parametric surfaces for K-times (K≥1) or merely lipschitz continuous one over triangles, rectangles or polygons. The capacity of its storage and the calculation are small. It is easily implemented on a microcomputer. An example is given by the DXY-880A plotter. 本文从分片线性逼近的基本思想出发,运用离散细分的手法,讨论了一般参数曲面的求交问题。利用插值逼近的误差估计,给出了一种可根据精度要求,事先确定细分次数的离散求交方法。该方法采用任意三角分划的分片线性逼近,避免了以每个子曲面的四个角点的拟合平面代替原子曲面,保证了分片线性逼近曲面的整体连续性,从而所得交线在逼近和光顺等方面的效果都比采用矩形分划的离散求交方法好。而且该方法可适用于三角域、矩形域或多边形区域上的任何K阶(K≥1)连续可微或者Lipschitz连续的参数曲面,具有较强的通用性,其算法所需的存贮量和计算量都较小,易于在微型计算机上实现。本文给出了一个由DXY-880A绘图机绘制的算法实例的图形。 This paper presents a new edge detection algorithm using the operator of Laplacian of binomial ( LOB).

This paper presents a new edge detection algorithm using the operator of Laplacian of binomial ( LOB). The image is smoothed by binomial distribution sequences. Then the Laplacian operation and zerocrossing detection are performed on the smoothed image to detect the edge points effectively. The LOB operator is derived and tbe fast algorithm of LOB edge detection is proposed. Even if the scale space constant n is smaller, the spectrum of LOB operator has better bandpass characteristics and high frequency attenuation performance. The zero-crossing points are detected successfully using 9-point plane fitting in the least squares sense. The slope threshold of fitting plane can be selected to extract the edge points and reduce the noise efficiently. 本文提出了一种用二项分布序列作为滤波模板,并相继进行拉普拉斯运算和零交点检测提取图象边缘的新的边缘检测算法。推导了二项分布——拉普拉斯边缘检测算子及实现卷积运算的快速算法。即使当尺度空间常数n较小时本文提出的算子亦具有较理想的带通特性及高频抑制性能。利用均方误差最小原理对被检测点邻域九点进行平面拟合可以成功地检测零交点,适当选择拟合平面斜率的检测阀值可大大消除噪声并有效地提取出图象边缘。 A new method is given which fair fitting plane data points for cubic rational Bézier curves.Fairness criterion is defined by the weighted average of the energy integral in this method. 研究了用有理Ｂéｚｉｅｒ曲线光顺拟合一组平面点列的问题．首先用三次Ｂéｚｉｅｒ曲线拟合平面数据点列，求得拟合Ｂéｚｉｅｒ曲线的控制顶点，然后在能量积分最小的条件下，通过最优化计算调整权因子，使所得到的曲线光顺 << 更多相关文摘 相关查询
