How can I read a text from an image file ?

I need to read a Text(Account Number) from a image file (.tif).
I tried the following approach :

try{
File newFile=new File("C:\\Image\\9R6-CCI\\09082010\\K08E091209FT_8021.tif");
BufferedImage buffImage=ImageIO.read(newFile);
ByteArrayOutputStream os= new ByteArrayOutputStream();
ImageIO.write(buffImage,IMAGE_TYPE,os);
byte []data=os.toByteArray();
String imageString=new BASE64Encoder().encode(data);
}catch (Exception e){}

But it was throwing problem. After googling, I found that ImageIO has some limitation to read an editable image.
Then, I tried the following approach :

try{File newFile=new File("C:\\Image\\9R6-CCI\\09082010\\K08E091209FT_8033.tif");
byte[] fileData = new byte[ (int)newFile.length()];
InputStream inStream = new FileInputStream( newFile);
inStream.read(fileData);
inStream.close();
String tempFileData = new String(fileData);
String imageString=new BASE64Encoder().encode(fileData);
}catch (Exception e){}

But i did n't get the desired out put . The Out put is as below.
xTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUxTFMUx

Please, help me to address the issue.

Thanks and Regards

Image files contain binary data - they can't be treated like character data. What's more, bitmap image formats (like TIFF, JPEG, GIF, PNG, etc.) do not contain any text they show in easily extractable form at all. Your best bet is to use an OCR package like Tesseract.

Hi Lester,

many many thanks for the useful responce.
I need some more details on your post to go ahead.

a) what is OCR package ? can i download it from internet ?
b) what is Tesseract. ?

Could you give me some examples on the issue?

Thanks again for the reply.

OCR = Optical Character Recognition. It has a Wikipedia page that should get you started.

Googling for Tesseract should find its home page pretty quickly; it's not like that's a common word.
