Hi! I am new in Java but decided to give a shot. I have to recognize some areas from image and extract text from that. I understand that Tesseract has those options (define searching area, using something like OnlyNumbers method and training option). I have tried Asprise but it seems that Tesseract is more accurate.
So far I did: Downloaded and unpacked files from http://tess4j.sourceforge.net to my PC under *C:\work\java\Tess4J*. I took and example *http://tess4j.sourceforge.net/codesample.html*, modified a bit and got code: package net.sourceforge.tess4j.example; import java.io.File; import net.sourceforge.tess4j.*; public class TesseractExample { public static void main(String[] args) { File imageFile = new File("c:\\work\\java\\pngs\\test1.jpg"); Tesseract instance = Tesseract.getInstance(); // JNA Interface Mapping //Tesseract1 instance = new Tesseract1(); // JNA Direct Mapping try { String result = instance.doOCR(imageFile); System.out.println(result); } catch (TesseractException e) { System.err.println(e.getMessage()); } } } Files: Directory of C:\work\java\Tess4J\src\net\sourceforge\tess4j\example 17.12.2013 20:08 <DIR> . 17.12.2013 20:08 <DIR> .. 17.12.2013 20:06 197 tess1.bat 17.12.2013 20:08 191 tess11.bat 26.12.2013 16:47 920 TesseractExample.class 17.12.2013 19:44 622 TesseractExample.java 4 File(s) 1 930 bytes 2 Dir(s) 73 354 510 336 bytes free C:\work\java\Tess4J\src\net\sourceforge\tess4j\example> It compiles without errors: C:\work\java\Tess4J\src\net\sourceforge\tess4j\example>javac -cp .; ..\..\..\..\..\lib\ghost4j-0.3.1.jar; ..\..\..\..\..\lib\jai_imageio.jar; ..\..\..\..\..\lib\jna.jar; ..\..\..\..\..\lib\junit-4.10.jar; ..\..\..\..\..\dist\tess4j.jar TesseractExample.java But when I am going to execute then: C:\work\java\Tess4J\src\net\sourceforge\tess4j\example>java -cp .; ..\..\..\..\..\lib\ghost4j-0.3.1.jar; ..\..\..\..\..\lib\jai_imageio.jar; ..\..\..\..\..\lib\jna.jar; ..\..\..\..\..\lib\junit-4.10.jar; ..\..\..\..\..\dist\tess4j.jar TesseractExample Exception in thread "main" java.lang.NoClassDefFoundError: TesseractExample (wrong name: net/sourceforge/tess4j/example/TesseractExample) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source) C:\work\java\Tess4J\src\net\sourceforge\tess4j\example> Am I missing some files or is the structure of files not correct??? -- -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
