Hi All,
I have installed the ocropus-0.3 version according to the instructions given
in the wiki site. Now I want to test the binarization methods. The main
procedure is given below:
the OCRopus source code is given in root/bstg/ocropus-0.3
I made a directory "imginvert" in the ocropus .
make a .cc file named "Otsu_Method" . and write code which is given below
-----------------------------------------------------------------------------
#include "iulib/imgio.h"
#include <ocropus/ocr-binarize-otsu.h>
using namespace ocropus;
using namespace colib;
using namespace iulib;
int main(int argc,char **argv)
{
bytearray image;
bytearray result;
autodel<IBinarize> binarizer (make_BinarizeByOtsu());
read_image_gray(image,argv[1]);
makelike(result,image);
binarizer->binarize(result,image);
write_image_binary(argv[2],result);
}
---------------------------------------------------------------
the command for compiling is
g++ Otsu_Method.cc -liulib -lSDL_gfx -lSDL -lpng -ljpeg
but when i entered this command , the following error come
/tmp/ccaKKgc2.o: In function `main':
Otsu_Method2.cc:(.text+0x1da): undefined reference to
`ocropus::make_BinarizeByOtsu()'
collect2: ld returned 1 exit status
Can anybody tell me , what this error meant, and how to solve it.
waiting for reply
Ainie
