Question

I am working on core application in blackberry in which I need to perform OCR task.

Till now I have searched and found out that there are few online API’s like ABBY which allows to read image and returns text file, but they are not free, after a few trails they charge a amount.

Can I perform Optical character recognition on device end completely with server implementation.
Please suggest me for this task.

EDITED: I am working with the following code

public String serverUrl = "http://cloud.ocrsdk.com";
    static final String BOUNDARY = "----------V2ymHFg03ehbqgZCaKO6jy";


    public byte[] send() throws Exception
    {
        HttpConnection hc = null;

        InputStream is = null;

        ByteArrayOutputStream bos = new ByteArrayOutputStream();

        byte[] res = null;

        try
        {
            hc = (HttpConnection) Connector.open(serverUrl+"/processImage/"+"language=en&exportFormat=txt");

            hc.setRequestProperty("Content-Type", "multipart/image-JPG; boundary=" + BOUNDARY);
            /*hc = (HttpConnection) Connector.open(SERVICE_URL);
            hc.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + BOUNDARY);
            hc.setRequestProperty(PARAM_IMAGE, "");
            hc.setRequestProperty(PARAM_LANGUAGE, lang);
            hc.setRequestProperty(PARAM_APIKEY, key);*/

            hc.setRequestMethod(HttpConnection.POST);

            OutputStream dout = hc.openOutputStream();

            dout.write(raw);

            dout.close();

            int ch;
            StringBuffer sb= new StringBuffer();
            is = hc.openInputStream();

            while ((ch = is.read()) != -1)
            {
                bos.write(ch);
                sb.append(ch);
            }
            System.out.println(sb);
            res = bos.toByteArray();
        }
        catch(Exception e){
            e.printStackTrace();
        }
        finally
        {
            try
            {
                if(bos != null)
                    bos.close();

                if(is != null)
                    is.close();

                if(hc != null)
                    hc.close();
            }
            catch(Exception e2)
            {
                e2.printStackTrace();
            }
        }
        return res;
    }

But even with this code its not working. I am getting 200 as response code after making HTTP request.
but not getting perfect response as expected the text. In response I am getting ERROR PAGE of ABBYY. http://cloud.ocrsdk.com/GenericError.htm?aspxerrorpath=/processImage/language=English&exportFormat=txt;connectionhandler=httpc

Please suggest me 🙁

Answer 1

I am done with the task OCR.

The code which I get from GitHub for Java is incomplete or may be not working from my side.
I have perform the implementation of OCR functionality on my PHP server.
And its working successfully.
