建议跳转查看最新版本博文:Face++与Java简单应用(新)
前几天看视频学习,看见了这个好东西,之前是那种只知道人脸识别技术但是根本没去了解是怎么实现的…
刚好趁着最近看看这是怎么个识别法。(其实只是用了他们的几个简单的方法,底层实现的真是厉害,采集数据不断学习不断分析…)
刚开始搜了一个网站大致了解了是个怎么的流程,这里我再自己梳理一下:
解压后这个文件夹里面可都是好东西,Demo里面是他的一个实例,FaceppSDK里面有个output文件则是测试必须要用的jar包
废话不多说了大晚上的也挺困的…直接上图了,我用的是eclipse for j2ee,工具不同这不是问题都差不多 由于用的是SpringMVC,配置啊什么的我就挑主要的发了
配置文件如下:springmvc.xml

web.xml就是基本配置
Controller层java文件代码如下:

import com.facepp.http.HttpRequests;
import com.facepp.http.PostParameters;
@Controller
public class UploadController {
@RequestMapping("/upfile.do")
public static ModelAndView upfile(MultipartFile uploadfile) throws IllegalStateException, IOException{
Picture pic=null;
StringBuffer sb=new StringBuffer();
//获得图片文件名
String filename=uploadfile.getOriginalFilename();
//防止文件夹名字重复
SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
//设置图片保存路径 保存在项目部署的路径
String path="C:"+File.separator+"Tomcat"+File.separator+"apache-tomcat-7.0.73"+
File.separator+"webapps"+File.separator+"spring-mvc"+File.separator+
"image"+File.separator+dateformat.format(new Date());
//System.out.println(filename);
File file=new File(path,filename);
//判断文件是否存在
if(!file.exists()){
file.mkdirs();
}
//将上传的文件写到磁盘
uploadfile.transferTo(file);
//储存在磁盘中的路径
String pp=path+File.separator+filename;
//System.out.println("pp:"+pp);
File fi=new File(pp);

}

}
}
jsp代码 一个是选择图片进行提交 另一个是转发后的jsp很简单只是一个展示:(以后可以换成类似ajax直接在同一页面输出)

照片只是网上随便copy下来的 人脸识别确实厉害啊..
革命尚未成功,同志仍需努力啊!
