Re: [tesseract-ocr] I can't get accurate ocr of this can anyone help with settings?

The whole point of a captcha is to evade automated reading. That's why letters are very close together and letters are heavily rotated off a consistent baseline. OCR is designed for normal text input so you need to do clever preprocessing here first. Sent from my iPhone > On 2 Jan 2017, at

Not sure it can but I wondered whether the scope of your legal regulation would allow: 1. Encrypt the user words file or store in your source code 2. In you wrapper program just before tesseract api init decrypt the file to tessdata 3. Init tesseract pointed to this file 4. Perform ocr 5.

What Tom said. However, let's assume all your variables are constant - resolution has to be just what you have, file format has to be TIF etc. then you can use a divide and conquer distributed computing pattern. That is, grab a machine that holds a queue of work and then make that queue farm

One option is try a different PSM mode - 6 may work well. Or you have a card which is great because it means you have repeatable areas of text. Processing the card into cropped areas is possible if your scanning is controlled. Look at what http://card.io do to see an example of getting a good

Do you have higher resolution images to work with - that's one issue going on here as the edges of your text are very fuzzy and at that resolution it's pretty hard for Tesseract. You can also play with Thresholding and Opening (Erosion/Dilation) to thicken some of your lines up (using e.g.
