Hey ! I am trying to make a template of my braille character set and I keep getting the following error. I used the same code for OCR and it works perfectly. What do I do ?
I am attaching the code herewith,
%Letter
A=imread('CharacterSet\a.bmp');B=imread('CharacterSet\b.bmp');
C=imread('CharacterSet\c.bmp');D=imread('CharacterSet\d.bmp');
E=imread('CharacterSet\e.bmp');F=imread('CharacterSet\f.bmp');
G=imread('CharacterSet\g.bmp');H=imread('CharacterSet\h.bmp');
I=imread('CharacterSet\i.bmp');J=imread('CharacterSet\j.bmp');
K=imread('CharacterSet\k.bmp');L=imread('CharacterSet\l.bmp');
M=imread('CharacterSet\m.bmp');N=imread('CharacterSet\n.bmp');
O=imread('CharacterSet\o.bmp');P=imread('CharacterSet\p.bmp');
Q=imread('CharacterSet\q.bmp');R=imread('CharacterSet\r.bmp');
S=imread('CharacterSet\s.bmp');T=imread('CharacterSet\t.bmp');
U=imread('CharacterSet\u.bmp');V=imread('CharacterSet\v.bmp');
W=imread('CharacterSet\w.bmp');X=imread('CharacterSet\x.bmp');
Y=imread('CharacterSet\y.bmp');Z=imread('CharacterSet\z.bmp');
%Number
one=imread('CharacterSet\1.bmp'); two=imread('CharacterSet\2.bmp');
three=imread('CharacterSet\3.bmp');four=imread('CharacterSet\4.bmp');
five=imread('CharacterSet\5.bmp'); six=imread('CharacterSet\6.bmp');
seven=imread('CharacterSet\7.bmp');eight=imread('CharacterSet\8.bmp');
nine=imread('CharacterSet\9.bmp'); zero=imread('CharacterSet\0.bmp');
letter=[A B C D E F G H I J K L M N O P Q R S T U V W X Y Z];
number=[one two three four five six seven eight nine zero];
character=[letter number];
templates=mat2cell(character,42,[24 24 24 24 24 24 24 ...
24 24 24 24 24 24 24 ...
24 24 24 24 24 24 24 ...
24 24 24 24 24 24 24 ...
24 24 24 24 24 24 24 24]);
save ('templates','templates')
clear all
What is the problem ? =O

Got the answer. The character set my mates gave me were 3D and I am using an 2D matrix

It would really help if you indicated which line errors, as I am sure you could guess if you put yourself in our shoes - but anyway...
If the error is on the line which assigns 'letter', then at least one of your CharacterSet images is not the same size as the others.
If the error is on the line which assigns 'number', then at least one of your CharacterSet images is not the same size as the others.
If the error is on the line which assigns 'character', then perhaps the 'letter' and 'number' variables aren't the same size.
.
.
By the way, you could do something much easier, like this:
T = char([97:122 48:57]);
templates = cell(1,length(T));
for ii = 1:length(T)
templates{ii} = imread(['CharacterSet\',T(ii),'.bmp']);
end

You are missing a ]. You have:
'[CharacterSet\',T(ii)
but you should have:
['CharacterSet\',T(ii),'.bmp']

Ya .. No. I made a mistake while typing it here. The error I get is this exactly,
Error using ==> imwrite at 394
Cannot open $#^#$% file for writing
