A captcha solver for really easy ones (don't expect it to solve recaptcha or any similar)

Tested on Ruby 2.2

gem install 'easy_captcha_solver'

Mac:

• Install Tesseract #=> brew install tesseract
• gem install 'tesseract-ocr'
• gem install 'mechanize'

Ubuntu:

• gem install 'tesseract-ocr'
• gem install 'mechanize'
• export TESSDATA_PREFIX=/usr/share/tesseract-ocr

If eng.traineddata is missing you can download it from : wget https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata

This gem uses Tesseract to read captchas, so obviously first of all you will need to install it.

Solve a captcha using an URL with image_url:

require 'easy_captcha_solver'

easy_c = EasyCaptchaSolver.new(image_url: "http://www.madrid.org/infi_pub/html/web/CargarCaptchaAccion.icm?idCaptcha=")
easy_c.captcha #=> "ABCDE"

You can also solve a captcha from your local using image_path:

require 'easy_captcha_solver'

easy_c = EasyCaptchaSolver.new(image_path: "./captcha_img.jpg")
easy_c.captcha #=> "ABCDE"
