A completely free and open source automatic verification code recognition system with self-learning function and a very high recognition rate for general verification codes.
The system uses the ZiilaaBrowser browser plug-in to capture verification code images, so it can be easily embedded into web pages. While maintaining the browser session environment, it can also read the verification code image only once (most verification codes are read every time (the reading results are all different), the dual functions of verification code image display and recognition can be realized. With the ZiilaaBrowser browser plug-in, the problem of Javascript cross-domain operations is also solved.
The automatic verification code identification system uses template matching method to identify verification codes. It has a powerful self-learning function and will automatically prompt users to add unknown graphics as templates to the template library.
The installation is extremely simple, just upload it to a WEB server with a PHP running environment. Then you can access it using a browser. Through the demonstration webpage of this system, anyone can embed it into any webpage through simple modifications. Since all source codes are open, various complex verification codes can be supported by modifying the code.
