How to use Golang to perform face recognition and face fusion on pictures

Face recognition and face fusion are common tasks in the field of computer vision, and Golang is used as An efficient and powerful programming language can also play an important role in these tasks. This article will introduce how to use Golang to perform face recognition and face fusion on images, and provide relevant code examples.

1. Face recognition

Face recognition refers to the technology of matching or identifying faces with known faces through facial features in images or videos. In Golang, we can use the third-party library dlib to implement the face recognition function.

First, we need to install the dlib library. You can use the following command:

go get github.com/Kagami/go-face

Next, we need to prepare the training set data. You can download already trained data sets such as shape_predictor_68_face_landmarks.dat from the dlib official website.

Then, we can write code to implement the face recognition function. The following is a simple example:

package main

import (
    "fmt"
    "image"
    "log"
    "os"

    "github.com/Kagami/go-face"
)

func main() {
    // 初始化人臉識別器
    rec, err := face.NewRecognizer("shape_predictor_68_face_landmarks.dat")
    if err != nil {
        log.Fatalf("無法初始化人臉識別器: %v", err)
    }
    defer rec.Close()

    // 加載待識別的圖片
    img, err := loadImage("face.jpg")
    if err != nil {
        log.Fatalf("無法加載圖片: %v", err)
    }

    // 識別人臉
    faces, err := rec.Recognize(img)
    if err != nil {
        log.Fatalf("無法識別人臉: %v", err)
    }

    // 輸出識別結(jié)果
    for _, f := range faces {
        fmt.Printf("識別到人臉，置信度: %f
", f.Confidence)
    }
}

func loadImage(filename string) (image.Image, error) {
    f, err := os.Open(filename)
    if err != nil {
        return nil, fmt.Errorf("無法打開圖片文件: %v", err)
    }
    defer f.Close()

    img, _, err := image.Decode(f)
    if err != nil {
        return nil, fmt.Errorf("無法解碼圖片: %v", err)
    }

    return img, nil
}

In the above code, we first initialize a face recognizer, then load the image to be recognized, and call the Recognize function to perform face recognition Identify. Finally, we output the recognition result, that is, the recognized face and its confidence.

2. Face fusion

Face fusion refers to combining the facial features of one person with the facial features of another person to generate a new image. In Golang, we can use the third-party library go-face-blender to implement face fusion.

First, we need to install the go-face-blender library. You can use the following command:

go get github.com/esimov/go-face-blender

Next, we can write code to implement the face fusion function. The following is a simple example:

package main

import (
    "image"
    "log"

    "github.com/esimov/go-face-blender"
)

func main() {
    // 加載源圖像和目標(biāo)圖像
    sourceImg, err := faceblender.LoadImage("source.jpg")
    if err != nil {
        log.Fatalf("無法加載源圖像: %v", err)
    }

    targetImg, err := faceblender.LoadImage("target.jpg")
    if err != nil {
        log.Fatalf("無法加載目標(biāo)圖像: %v", err)
    }

    // 提取源圖像和目標(biāo)圖像中的人臉特征點
    source, err := faceblender.ExtractFace(sourceImg)
    if err != nil {
        log.Fatalf("無法提取源圖像中的人臉特征點: %v", err)
    }

    target, err := faceblender.ExtractFace(targetImg)
    if err != nil {
        log.Fatalf("無法提取目標(biāo)圖像中的人臉特征點: %v", err)
    }

    // 進(jìn)行人臉融合
    resultImg, err := faceblender.BlendFace(source, target)
    if err != nil {
        log.Fatalf("無法進(jìn)行人臉融合: %v", err)
    }

    // 保存融合后的圖像
    err = faceblender.SaveImage(resultImg, "result.jpg")
    if err != nil {
        log.Fatalf("無法保存融合后的圖像: %v", err)
    }
}

In the above code, we first load the source image and the target image, and extract the face feature points in them respectively. Then, we call the BlendFace function to perform face fusion, and save the fused image through the SaveImage function.

Summary:

This article introduces how to use Golang to perform face recognition and face fusion on images, and provides corresponding code examples. I hope this article can be helpful to developers who use Golang for computer vision tasks. Of course, in addition to third-party libraries such as dlib and go-face-blender, there are many other libraries that can also achieve similar functions. Readers can choose the appropriate library for development according to their own needs.
