Sharing of practical experience in Go language development and implementation of face recognition system

Abstract: Face recognition technology has been widely used in current society. This article will share the author’s experience in The practical experience of using Go language to develop a face recognition system, including key steps such as face detection, feature extraction, comparison, as well as problems encountered and solutions, I hope it will be helpful to relevant developers.

Keywords: Go language, face recognition, feature extraction, system development

1. Introduction

With the development of artificial intelligence technology, face recognition technology has become It has become a part of life and is used in various aspects such as access control systems, security monitoring, and face payment. In response to the needs of this technology, the author decided to use Go language to develop the face recognition system. This article will share the practical experience in this process.

2. Basics of face recognition

1. Face detection

The first step of face recognition is face detection, that is, from images or videos Find the location of a face in the stream. The author uses the OpenCV library in the Go language for face detection, and implements the face detection function by calling relevant APIs.

2. Facial feature extraction

After obtaining the face position, it is necessary to extract the features of the face, which are used to distinguish different faces. The author uses the DLib library to extract facial features and uses related packaging libraries in the Go language.

3. Face comparison

Once the features of the face are extracted, different faces can be compared to determine whether they are the same person. In actual development, the author used some open source face comparison algorithms, such as FaceNet, etc.

3. Practical experience sharing

1. Platform adaptability issues

In the Go language, due to the relatively small number of open source libraries, it is necessary to Consider compatibility with the underlying C/C library. During the development process, the author encountered some platform adaptability issues and needed to adapt to different operating systems.

Solution: The author learned some skills about the adaptation of Go language and C/C library by consulting relevant information, and finally successfully solved the problem of platform adaptability.

2. Performance Optimization

Since face recognition involves a lot of image processing and calculations, performance optimization is a key issue. In the initial version, the performance of the face recognition system was not ideal and needs further optimization.

Solution: The author improved the performance of the face recognition system by optimizing the algorithm and using multi-threaded parallel computing. At the same time, he also used some optimization techniques of the Go language.

3. Model training

In the face recognition system, model training is an important link and requires a large amount of training data and computing resources. In practice, the author encountered problems in model training, including data set selection, training parameter tuning, etc.

Solution: The author conducted a lot of research and experiments on the model training problem, and finally solved the model training problem by adjusting training parameters and increasing training data.

4. Summary and Outlook

Through the practice of using Go language to develop face recognition systems, the author has accumulated rich experience, including key steps such as face detection, feature extraction, and comparison. Problems encountered and solutions, etc. In the future, the author will continue to study face recognition technology in depth and apply it to more practical scenarios, such as intelligent security, face payment and other fields.

In short, the Go language has demonstrated good applicability and flexibility in the development of face recognition systems. Through continuous practice and exploration, I believe that a more efficient and stable face recognition system can be developed to benefit society. Life brings greater convenience and security.
