gprmax-tools
GprMax的理论基础是时域有限差分(FDTD)方法。时域有限差分方法直接将Maxwell方程作差分离散，利用二阶精度的中心差分近似把Maxwell方程中的微分算符直接转换为差分形式，在空间和时间上对电场和磁场交替间隔取样，使计算过程完全模拟电磁波逐步传播以及与目标物体相互作用的过程。(GprMax is based on the theory of the finite difference time domain (FDTD) method. The finite difference time domain method directly will Maxwell equation of discrete difference, using second order precision of the central difference in the equations are Maxwell approximate differential operator directly convert difference forms, in the space and time of electric field and magnetic field on alternate sampling interval, making the calculation process simulation electromagnetic wave propagation and completely step by step and target object interaction process. )

3x3-neighbor-pixel
Description
All the filters have needed neighbor data the current pixel in the image,here this function(res_window=cover_window(how many neighbor value for row ,how many neighbor value for column ,input image) produce the result( res_window(row,col,total size))
input
inp_img=2d data(row * col)
w=cover size
w=[3 3] = 3x3 cover pixel generation
output
o_img=result 3d
o_img(w(1),w(2),r*col)
if
inp_img=[1 2 3 4 5 6 ]
w=[3 3]
Soloution
it will construct new image
new_img=[0 0 0 0 0 0 1 2 3 0 0 4 5 6 0 0 0 0 0 0]
result
o_img(:,:,1)=[0 0 0 0 1 2 0 4 5]
o_img(:,:,2)=[0 0 0 1 2 3 4 5 6]
finally
o_img(1:3,1:3,6)
example
a=imread( pears.png )
b=rgb2gray(a)
c=cover_window( b,[3 3]) 3x3 window construction
