I have a code 39 barcode image.

Because each character is encoded by a Code 39 total of 9 elements. In which five black bars and 4 spaces, 3 of 9 elements with large width (2 large black bars and a big blank) 6 remaining elements have small widths (narrow (except 4 characters $, /, +% have three large white lines). I want to extract characters from the original bar code of the individual characters.

My images was taken on the binary image, 0 is black bars, 1 is white bars

I use the following command to cut the first letter

for j=1:n,
    if (I(:,j)==0)&(I(:,j+1)==1)
        s=s+1;
        if s==5
            C0 =I(:,1:j+2);
            C0a=imresize(C0,[49 50]);
            imwrite(C0a,'Tapanh\1.bmp');      
            s=0;
            t=j+2;
            break;
        end
    end
end

I want to use the loop to cut each letter next to the end. Please help me. This is my sample image and images need to be cut http://s1213.photobucket.com/albums/cc477/bluesrose/barcode/ please help me

Use bwconncomp to group objects and then use regionprops with the 'image' option. Each image in the output from regionprops will be a an image of that object (letters & bars).
