Java实现人脸识别

飞熊 • • 后端漫谈 • 阅读 279

生活中，最使人疲惫的往往不是道路的遥远，而是心中的郁闷;最使人痛苦的往往不是生活的不幸，而是希望的破灭;最使人颓废的往往不是前途的坎坷，而是自信的丧失;最使人绝望的往往不是挫折的打击，而是心灵的死亡。所以我们要有自己的梦想，让梦想的星光指引着我们走出落漠，走出惆怅，带着我们走进自己的理想。

导读：本篇文章讲解 Java实现人脸识别，希望对大家有帮助，欢迎收藏，转发！站点地址：www.bmabk.com，来源：原文

前言

最初使用虹软视觉开放平台提供的免费SDK接入人脸识别功能，由于对人脸识别有着浓厚的兴趣，于是后来又写了2篇内容更全例子更详细的文章，欢迎阅读。

平台准备

利用虹软视觉开放平台提供的免费SDK即可快速接入人脸识别功能

官网:https://ai.arcsoft.com.cn/

创建应用

Java实现人脸识别

添加SDK

选择服务

Java实现人脸识别

选择运行平台

Java实现人脸识别

添加SDK后,还可添加多个不同平台的SDK

Java实现人脸识别

安装SDK

下载SDK

解压SDK,如解压ArcSoft_ArcFace_Java_Windows_x64_V3.0.zip

进入ArcSoft_ArcFace_Java_Windows_x64_V3.0\libs目录

在此目录进入cmd进行安装Jar到本地仓库

mvn install:install-file -DgroupId=com.arcsoft.face -DartifactId=arcsoft-sdk-face -Dversion=3.0.0.0 -Dpackaging=jar -Dfile=arcsoft-sdk-face-3.0.0.0.jar

指定运行库位置

将ArcSoft_ArcFace_Java_Windows_x64_V3.0\libs目录下的子目录文件拷贝至特定目录,如:D:\libs\

示例代码测试

添加依赖

    <dependency>
            <groupId>com.arcsoft.face</groupId>
            <artifactId>arcsoft-sdk-face</artifactId>
            <version>3.0.0.0</version>

人像检测

    public boolean checkIsPortrait(ImageInfo imageInfo) {

    @Test
    public void test(){
        File file = new File("D:\\test.jpg");
        ImageInfo imageInfo = ImageFactory.getRGBData(file);
        boolean checkIsPortrait = this.faceEngineService.checkIsPortrait(imageInfo);
