Recently I was wondering if I don't have a tool for image text recognition? I think of OCR, which is quite awesome in China. Can python be used for implementation?

The verification code needs to be recognized when writing a program these days, because the program is written in Python and naturally intends to use Python to identify the verification code. The following describes how to implement the Program on the script home platform. If you are interested, you can refer to a popular tool that has previously been written to the School Intranet, Java (and Java programs

Tesseract-OCR is an OCR engine developed by the HP lab from 1985 to 1995. Later, it was developed by Google and open-source. It supports multiple platforms and supports up to 40 languages, including Chinese, supports training. Tesseract-OCR is a command line.ProgramBut it also provides wrapper in multiple languages, such as. net., Python, Ruby, C, and Java to facilitate integration into programs. The command line call is simple: Tesseract.exe

hit the code and the clarity of the lectures, but also can feel the teacher is a professional level of teaching.-Concluding remarksThis is the end of the first blog post record. For the study, will be sophomore I was full of enthusiasm, hey, accidentally exposed to the age. Learning methods, learning process is the main entry point of this article, if there is also just beginning to learn Python classmate, can exchange. Hope that the next study will

For python verification code recognition, there are several main methods: one is to process the image, and then use the font feature matching method. The other is to create a character matching dictionary after image processing, another type is recognition using ocr module directly. No matter what method is used, you need to process the image first, so try to ana
