Bypass Captcha using 10 lines of code with Python, OpenCV & Tesseract OCR engine

test.py

import cv2.cv as cv
import tesseract
gray = cv.LoadImage('captcha.jpeg', cv.CV_LOAD_IMAGE_GRAYSCALE)
cv.Threshold(gray, gray, 231, 255, cv.CV_THRESH_BINARY)
api = tesseract.TessBaseAPI()
api.Init(".","eng",tesseract.OEM_DEFAULT)
api.SetVariable("tessedit_char_whitelist", "0123456789abcdefghijklmnopqrstuvwxyz")
api.SetPageSegMode(tesseract.PSM_SINGLE_WORD)
tesseract.SetCvImage(gray,api)
print api.GetUTF8Text()

@forum2k9 I solved the first one with convert and Tesseract:

$ convert ofdbmf.jpg -colorspace Gray -blur 0 -level 0,60% ofdbmf-1.jpg
$ tesseract -psm 8 ofdbmf-1.jpg -
OFDBMF

I posted the details at https://mathieularose.com/decoding-captchas

It's done, but it work only with the type of captcha I posted here, If you want me to make a model for your type of captcha, I need a dataset with at least 10k captcha.
If you don't have it, send me an image, I'll find how to gen a lot of captcha, make a model then tell you how to use it.

@NotTrueFalse hey : those kind of captchas are automatically generated by https://captcha.com/java-captcha.html. You could get millions of such annotated captchas.

Thank you, I'll make another branch so you can generate another type or captcha, I'll have to update the pre-processing part though but it should be fine.

@NotTrueFalse my intent wasn t generating the dataset myself.

You want me to do all the step to create the model? At this point I could just create a website and make a cheap api for people

@NotTrueFalse I lack the knowledge to train an ai and I m bad at advanced databases scenarios.
