Oblique effect filter (OEF) 三维曲面--MATLAB代码：

1. % create a discrete FIR digital oblique effect filter(OEF)
   
2. clc,clear,close all
   
3. f = -60:1:60;
   
4. cita = -60:1:60;
   
5. [F,CITA] = meshgrid(f,cita);
   
6. r = 0.348;  % 3.48;
   
7. lamda = 13.57;
   
8. for i=1:size(F,1)
   
9.     for j=1:size(F,2)
   
10.         if (abs(F(i,j))>r)
    
11.             OEF(i,j) = 1-( 1-exp( -(abs(F(i,j))-r)/lamda ) ) * sin( 2*CITA(i,j)*pi/180 ) * sin( 2*CITA(i,j)*pi/180 );
    
12.         else
    
13.             OEF(i,j) = 1;
    
14.         end
    
15.     end
    
16. end
    
17. mesh(F,CITA,OEF);
    
18. axis tight;
