and similar technologies are not panacea. Faced with carefully designed complex verification codes, the recognition rate of deep learning and OCR can be disappointing.
But that doesn't mean giving up on your efforts. With the development of technology and the improvement of data sets, verification code cracking technology is expected to make breakthroughs in the future. Continuous attention and experimentation of new technologies and tools are the key to cracking verification codes.
