Hi at all,
first, sorry for the bad english...
i have to calculate the mean of an image without using the command "mean".
with mean i resolve in this way:
[code]a=imread('x.JPG');
[M,N]=size(a);
%mask 5x5
for i=1:M-4
for j=1:N-4
c = a(i : i+4 , j : j+4);
media5(i,j)=mean( c ( : ) );
end;
end;[/code]
the teacher says that shoul be used more for-cycle, but i have no idea about how implement it.
Thanks in advance
