Brief Introduction

MNIST是一个应用广泛的手写数字数据集。请参考http://yann.lecun.com/exdb/mnist/ 了解不同算法识别MNIST库的结果比较。

CAPTCHA是一个自动生成验证码的Python库。

Tesseract-OCR是一个OCR识别的Python库。

Pillow是一个图像处理的Python库。

OpenCV是一个计算机视觉库,cv2是对应的Python包。

深度学习也经常被用在图像识别中,常见的库有Tensorflow,PyTorch, keras等。

Augmentor库是机器学习中训练图像识别的利器。在你有少数样本的情况下,可以通过对原始验证码的变换,来拓展你的训练数据集
