这也是我在索贝尔和拉普拉斯边缘检测教程，但我只是想再次强调这一点的，为什么你会要检测的边缘。
This was also stated in my Sobel and Laplace edge detection tutorial, but I just wanted reemphasize the point of why you would want to detect edges.
本文提出平面上拉普拉斯算子在一类平行六边形网格上的成对4点差分格式。
In this paper we propose so-called coupled 4-point difference schemes for the Laplacian operator over a class of parallel hexagon partitions of the plane.
首先用点源函数和格林函数法，推导出拉普拉斯空间线源解。
This paper presents the solutions in Laplace space derived by point-source function and Green's function.
在矩形网格上的九点差分近似的正确公式。使用它，在均质情况下，对拉普拉斯方程、布阿松方程和热传导方程可以构造出高阶精度的差分近似。
Under homogeneous conditions, the application of this equation may give a differential approximation of high order accuracy for Lapace equation, Poisson equation and heat conduction equation.
