At present, with the development of science and technology, a lot of new technologies have been developed, which has brought great convenience to people's lives. Face recognition technology is a very innovative technology. Therefore, in the field of computer science, professionals have been studying the related technologies. And the technology has been applied in the fields of industry and biology. In this paper, a deep analysis of the theory of face recognition was made. Through the gabor wavelet and memetic ecological algorithm, the technology was further studied.
