I write java code to execute tesseract.exe.

How to make tesseract to recognize those numbers better?

You can see, my result is not so good:

297 20 32 33 34 35 36 734

37 37 38 .38 39 39 40 41 4124

443 443

What can I do to improve it?

Tesseract requires an image to be of minimum of 300 X 300 dpi for good results.

I would suggest to resize the image and apply a filter for improvement in detection.

I generally use imagemagick for this purpose.
