I have an image where I crop on the region that I have set to recognize by ocr using tesseract. After all the image processing the result is like this Image before processing

When this image is given to do ocr, the result is not accurate like

Image 7_B7.bmp = W’ I WTH 3795 ’ _/ 7777777777” f ‘ .1.“ we)? 1

What I want to do is to make the image to be like this(edited in paint) Expected result of preprocessing

so that it will give more accurate result after recognition. What can I do to get image like this?
