Hi,
i have used the code below to add gaussian noise to the mat file.
load C:\video_sim\test_seq\football\football
frames=org_football;clear org_football
dim_f=size(frames(:,:,1));
len=length(frames(1,1,:));
strt=1;stp=len;
var_n=(10)^2;
randn('state',0);
for j = strt:stp
v1=randn(dim_f);
v2=v1-mean(v1(

;
noise(:,:,j)=sqrt(var_n)*v2/cov(v2(

;
end
nsy_frames=frames+noise;
clear noise frames
now i would like to add impulse noise along with the gaussian noise
could u please tell me how to do it.
