ocr

问题 I have an image which is blurred: This is a part of the business card and it is one of the frames taken by the camera and without proper focus. The clear image looks like this I'm looking for the method which could give me an image of better quality, so that image could be recognized by OCR, but also should be quite fast. Image is not blurred too much (I think so) but isn't good for OCR. I tried: different kinds of HPF, Laplacian, Canny detector, combinations of morphological operations
