It has been nearly three months since the previous blog titled automatic identification of simple verification Codes Using gocr. Recently, verification codes have been cracked again, but this time, the verification code is more complicated. gocr is not powerful enough. The accuracy of pure digital recognition is indeed high, but the mixed numbers and letters cannot be handled. So
There are many ways to get tesseract source code. You can get it directly from repo, or you can download a compressed package. However, there are often strange problems when compiling. Here is how to simply configure and compile the source code. Reference original: How to Build tesseract OCR Library on Windows Compiling tesse
