Iterative approximation algorithm of Hessian matrix in structural optimization;
结构优化中的海森矩阵的近似迭代方法
The Hessian matrix of every function in this model is constant, so it will be calculated once in the entire optimal process based on interior point method, which speeds up each iteration.
该新模型的海森矩阵是精确的常系数矩阵,在内点法迭代过程中只需要计算一次,从而缩短了每次迭代的计算时间。
Then, Hessian matrix was used to eliminate unstable edge points.
该算法基于FAST算法,首先对角点进行粗提取,即如果某点为候选角点,那么在该点的某个圆形邻域的圆周上应有足够多的点,这些点的灰度值与该点的灰度值之差的绝对值应大于自适应阈值;然后利用海森矩阵去除不稳定的边缘点;最后计算候选角点周围邻域内像素点的拉普拉斯值,只有取得拉普拉斯极值的候选点才能最终确定为角点,进一步剔除了虚假角点。
Respective characteristics and styles of the achievements attained by the master physicians: Dirac and Heisenberg, have been discussed in the history of the top three physic achievements in 19 th century: thermodynamics, electromagnetics and statistic dynamics.
