??? Index exceeds matrix dimensions...

am gettin an error in 33rd line-title('Looking for ...','FontWeight','bold','Fontsize',16,'color','red');..

can some1 help me

code:

w=load_database();

prompt={'compare'}; 
title='IMAGE INPUT';
ans=inputdlg(prompt,title);
if ~isempty(ans{1})
r1 = str2num(ans{1});
if isempty(r1)
ri =round (400*rand(1,1));
end
end

r=w(:,r1);                          
v=w(:,[1:r1-1 r1+1:end]);           
N=20;                               
O=uint8(ones(1,size(v,2))); 
m=uint8(mean(v,2));                 
vzm=v-uint8(single(m)*single(O));   
L=single(vzm)'*single(vzm);
[V,D]=eig(L);
V=single(vzm)*V;
V=V(:,end:-1:end-(N-1));            

cv=zeros(size(v,2),N);
for i=1:size(v,2);
    cv(i,:)=single(vzm(:,i))'*V;    
end

subplot(121); 
imshow(reshape(r,112,92));
title('Looking for ...','FontWeight','bold','Fontsize',16,'color','red');
subplot(122);
p=r-m;                              
s=single(p)'*V;
z=[];
for i=1:size(v,2)
    z=[z,norm(cv(i,:)-s,2)];
    if(rem(i,20)==0),imshow(reshape(v(:,i),112,92)),end;
    drawnow;
end

[a,i]=min(z);
subplot(122);
imshow(reshape(v(:,i),112,92));title('Found!','FontWeight','bold','Fontsize',16,'color','red');

Edit the code before you post the code use {}button at the top for editing

It is also likely that one needs the data too and not only the code to figure it out

[Babak]

doesn't give me error when I ran it. I only ran that line which is correct. I don't know what is

 w=load_database();

so can't run your script.

You can find the database at the follwoing link, % http://www.cl.cam.ac.uk/research/dtg/attarchive/facedatabase.html

Answer 1

[Walter Roberson]

Your line

title='IMAGE INPUT';

is making "title" into a variable, conflicting with your attempt to use title() as a function later.

[geethi]

sir i tried to make both variables..but its not workin

[Walter Roberson]

Change your lines

title='IMAGE INPUT';
ans=inputdlg(prompt,title);
if ~isempty(ans{1})
r1 = str2num(ans{1});

to

inputtitle='IMAGE INPUT';
userans=inputdlg(prompt,inputtitle);
if ~isempty(userans{1})
r1 = str2num(userans{1});

[geethi]

the same error is coming

[DGM]

If this is a plain script with no variable cleanup at the beginning, then the problem will persist until the variable called title is cleared.

clear title
