Baidu AI interface and Golang: realize face comparison and make applications more intelligent
Abstract:
Face comparison is widely used in modern technology An important task, it can be used in areas such as face recognition and identity verification. This article will introduce how to use Baidu AI interface and Golang programming language to implement the face comparison function, and help readers get started quickly through simple code examples.
Introduction:
In today's society, face comparison has become a basic requirement for intelligent applications. In the past, only traditional cameras acquired images, and face recognition or identity verification was achieved through simple image processing. However, this method has many limitations, such as the influence of light, angle, expression and other factors. Nowadays, with the rapid development of artificial intelligence technology, through deep learning algorithms, face comparison can be performed more accurately. This article will introduce how to use Baidu AI interface and Golang programming language to implement an application based on face recognition.
Prerequisite preparation:
Before we start, we need to ensure that we have the following conditions: Baidu AI developer account and installation of the Golang programming environment.
Step 1: Registration and configuration of Baidu AI interface
Step 2: Golang dependent library installation
Execute the following command to install the required dependent libraries:
go get -u github.com/levigross/grequests
Step 3: Write Golang code
Import the required dependent libraries:
package main import ( "fmt" "github.com/levigross/grequests" )
Define a function in the code to send an HTTP POST request and obtain the response from the Baidu AI interface :
func request(url, apiKey, apiSecret, imageURL string) (string, error) { options := &grequests.RequestOptions{ Data: map[string]string{ "api_key": apiKey, "api_secret": apiSecret, "image_url_1": imageURL, "image_url_2": imageURL, }, } resp, err := grequests.Post(url, options) if err != nil { return "", err } if resp.Error != nil { return "", resp.Error } return resp.String(), nil }
Call the function defined above in the "main" function and output the response result of Baidu AI interface:
func main() { apiKey := "<your-api-key>" apiSecret := "<your-api-secret>" imageURL := "<your-image-url>" url := "https://api-cn.faceplusplus.com/facepp/v3/compare" result, err := request(url, apiKey, apiSecret, imageURL) if err != nil { fmt.Println("Error:", err) } else { fmt.Println(result) } }
Step 4 : Run the program
Execute the following command to run the program:
go run main.go
Conclusion:
Through the combination of Baidu AI interface and Golang programming language, we can easily realize the face comparison function. In actual applications, readers can expand and optimize according to their own needs, such as adding image processing and other functions to achieve more intelligent applications. I hope this article can help readers better understand and use Baidu AI interface and Golang programming language.
