火得不要不要的人工智能，SpringBoot实现人脸识别功能

**人脸识别系统基于Spring Boot**

在本文中，我们将使用Spring Boot构建一个简单的人脸识别系统。这个系统将能够识别已知的人脸，并对未知的人脸进行分类。

###依赖项首先，让我们定义我们的Maven依赖项：

xml<dependencies>
 <!-- Spring Boot -->
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>

 <!-- 人脸识别 -->
 <dependency>
 <groupId>com.github.luggit</groupId>
 <artifactId>face-api</artifactId>
 <version>3.0.0</version>
 </dependency>

 <!-- JSON处理 -->
 <dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
 </dependency>
</dependencies>

java// FaceModel.javaimport org.springframework.stereotype.Component;

@Componentpublic class FaceModel {
 private final FaceAPI faceAPI;

 public FaceModel(FaceAPI faceAPI) {
 this.faceAPI = faceAPI;
 }

 public String identifyFace(byte[] imageBytes) throws Exception {
 // 加载模型 MTCNN mtcnn = new MTCNN();
 Detection detection = mtcnn.detect(imageBytes);

 // 检测人脸 if (detection != null && detection.size() >0) {
 Face face = faceAPI.extractFace(detection.get(0));
 return face.toString();
 } else {
 return "未知的人脸";
 }
 }
}

java// FaceController.javaimport org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestControllerpublic class FaceController {
 private final FaceModel faceModel;

 public FaceController(FaceModel faceModel) {
 this.faceModel = faceModel;
 }

 @PostMapping("/identify")
 public String identifyFace(@RequestBody byte[] imageBytes) throws Exception {
 return faceModel.identifyFace(imageBytes);
 }
}

java// FaceResult.javaimport com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class FaceResult {
 @JsonProperty("face_id")
 private String faceId;

 public FaceResult(String faceId) {
 this.faceId = faceId;
 }

 public String getFaceId() {
 return faceId;
 }
}

bashPOST /identify HTTP/1.1Content-Type: application/octet-stream// 图像数据

json{
 "face_id": "已知的人脸"
}
