urp-decaptcha

Python application to break captcha of URP（University Resource Plan）System , using OpenCV(2.1)

Prerequisites

• pip
• python-opencv (see python-opencv tutorial for more details)

How to Use

Clone the code to your local project by

# git clone git@github.com:JetMuffin/urp-decaptcha.git

Install dependencies

# cd urp-decaptcha
# pip install -r requirements

Complete usage:

Usage: decaptcha.py [options]

Options:
  -h, --help            show this help message and exit
  -s SHOW, --show=SHOW  show input image
  -b SHOW_BINARY, --show_binary=SHOW_BINARY
                        show binary image of input
  -t TRAIN_DATA, --train_data=TRAIN_DATA
                        path of train data

How to use this in your code

Use existing image to train classification model

  segmenter = NormalSegmenter()
  extractor = SimpleFeatureExtractor(feature_size=20, stretch=False)
  analyzer = KNNAnalyzer(segmenter, extractor)
  analyzer.train('data/features.jpg')

• Use classification model to test your own images

  result = analyzer.analyze('data/example.jpg')
