hello.. iam stuck over here on function gabor
function [out1 out2] = fn_gabor(c)
alpha = 1/sqrt(2);
t=1;
for teta = pi/8:pi/8:pi;
for j = 2:5;
for x = -8:8;
for y = -8:8;
h = exp((-alpha^(2*j))*(x^2 + y^2)/2);
HI (x+9,y+9)= h;
Re = cos (pi*(alpha^j)*(x*cos(teta)+ y*sin(teta)));
RI (x+9,y+9)= Re;
Im = sin (pi*(alpha^j)*(x*cos(teta)+ y*sin(teta)));
II (x+9,y+9)= Im;
end;
end;
Rh = HI*RI;
Rh;
Ih = HI*II;
Ih;
R = conv(in,Rh);   %%%ERROR IN HERE
I = conv(in,Ih);
% Normalisasi
Ro = (R)/(max(max(R)));
Roa = mean (Ro);
Roav = mean (Roa);
Io = (I)/(max(max(I)));
Ioa = mean (Io);
Ioav = mean (Ioa);
% Magnitude hasil konvolusi
out = sqrt (Ro*Ro' + Io*Io');
outfil(t) = sqrt (Roav*Roav + Ioav*Ioav);
t = t + 1;
end;
end;
out1 = out;
out2 = outfil;
