  • A method of plotting the isovalue line of implicit functions by computer is introduced, the comparison of our method with traditional method of intensity scaling is given . by using of our method, some examples of isopotential and interference in college physics are displayed
    通过介绍有关隐函数等值线的计算机绘制方法,与传统的物理图形强度定标法作了比较.用此方法举例模拟了大学物理课程内容中电荷等势线和波的干涉图象
  • Paper [ 76 ] provides a integer algorithm for rasterizing free curves, we need change the curve form to implicit function form, then use curve's positive-negative property to draw, but we ca n't use this algorithm when curve's degree is higher than 3 and this algorithm ca n't avoid using multiplication; paper [ 77 ] provides a new generating algorithm, this algorithm can draw bezier very well, but for b-spline curve, we need use convert them into bernstein base form . because this process spends a lot of time, this algorithm has not a good speed and effect for rendering rational b-spline curve
    现在经常采用的算法也是基于几何的算法(即线式生成算法)和基于像素的算法(点式生成算法);文献78]提供了一种有理参数曲线的快速逐点生成算法,该算法对有理b吮ier曲线的绘制,能起到很好的作用,但是对于有理b样条曲线,必须先通过多项式的代数基与bemstein基间的变换矩阵,把原式用bemstein基表示,这一过程由于计算量大,降低了曲线生成的速度和效率
  • This dissertation proposes an algorithm to detect edges and extract contours from medical images based on quadric spline wavelets transform . the algorithm can generate single, continuous and close contours . there are two main methods of surface reconstruction ? explicit connecting contours method and implicit function method
    利用小波变换良好的局部化特性和其固有的多尺度特性,具体针对医学图象边缘轮廓提取的特点,提出一种基于二次样条小波变换的边缘检测和轮廓提取方法,提取出单像素和连续封闭的边缘轮廓。
  • The original flow rate formula of parobolic throat flume used for u-shaped channel is implicit function and is not convenient for calculation in irrigation districts . an simplified formula is developed in this paper, with a di fference between results calculated with the original formula and the new formul a being less than 0.5 %
    用于u形渠道量水的抛物线形喉口式量水槽原流量公式为隐函数形式,针对其使用不便的现状,通过理论分析推导出了显函数形式的量水槽流量公式,计算结果与原流量公式比较相对误差值0.5%。
  • In latter part of chapter three, some exciting properties of the revised lagrangian function discussed first, which leads to form a dual algorithm of cora or cot . convergence theorem proved by banach perturbation theorem, bertsekas implicit function theorem ii and by analyzing hesse matrix of revised largrangian function
    另一类是构造相应的lagrange函数及其一种对偶算法的迭代格式,讨论了修正lagrange函数的性质,并借助banach扰动定理及bertsekas第h隐函数定理,及对修正lagrange函数hesse阵分析,证明了该算法的收敛性
