Java调用百度AI实现人体属性分析

好久没有更新了...闲来无事发一下模仿百度AI的人体属性分析。

百度AI效果图如下：

本人开发效果图如下：

界面大家可以忽略........下面讲讲代码实现

1、Base64ImageUtils.java 实现图片解码功能

package com.lzw.utils;import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;import java.util.Base64.Encoder;
import java.util.Base64;
import java.util.Base64.Decoder;/*** Created by lzw on 2019/8/29.* 本地或者网络图片资源转为Base64字符串*/
public class Base64ImageUtils {/*** @Title: GetImageStrFromUrl* @Description: 将一张网络图片转化成Base64字符串* @param imgURL 网络资源位置* @return Base64字符串*/public static String GetImageStrFromUrl(String imgURL) {byte[] data = null;try {// 创建URLURL url = new URL(imgURL);// 创建链接HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.setRequestMethod("GET");conn.setConnectTimeout(5 * 1000);InputStream inStream = conn.getInputStream();data = new byte[inStream.available()];inStream.read(data);inStream.close();} catch (IOException e) {e.printStackTrace();}// 对字节数组Base64编码//BASE64Encoder encoder = new BASE64Encoder();Encoder encoder = Base64.getEncoder();// 返回Base64编码过的字节数组字符串// return encoder.encode(data);return encoder.encodeToString(data);}/*** @Title: GetImageStrFromPath* @Description: (将一张本地图片转化成Base64字符串)* @param imgPath* @return*/public static String GetImageStrFromPath(String imgPath) {InputStream in = null;byte[] data = null;// 读取图片字节数组try {in = new FileInputStream(imgPath);data = new byte[in.available()];in.read(data);in.close();} catch (IOException e) {e.printStackTrace();}// 对字节数组Base64编码//BASE64Encoder encoder = new BASE64Encoder();Encoder encoder = Base64.getEncoder();// 返回Base64编码过的字节数组字符串// return encoder.encode(data);return encoder.encodeToString(data);}/*** @Title: GenerateImage* @Description: base64字符串转化成图片* @param imgStr* @param imgFilePath  图片文件名，如“E:/tmp.jpg”* @return*/public static boolean saveImage(String imgStr,String imgFilePath) {if (imgStr == null) // 图像数据为空return false;// BASE64Decoder decoder = new BASE64Decoder();Decoder decoder = Base64.getDecoder();try {// Base64解码//byte[] b = decoder.decodeBuffer(imgStr);byte[] b = decoder.decode(imgStr);for (int i = 0; i < b.length; ++i) {if (b[i] < 0) {// 调整异常数据b[i] += 256;}}// 生成jpeg图片OutputStream out = new FileOutputStream(imgFilePath);out.write(b);out.flush();out.close();return true;} catch (Exception e) {return false;}}
}

2、HttpClientUtils.java 自己编写调用百度API 接口工具类

package com.lzw.utils;import org.apache.http.*;

3、BodyAPITest.java

在控制台就可以看到从百度AI调回来的信息，要进一步操作的话就需要对这么信息进行json解析这个就不详细讲了有需要的评论区留言吧项目需要的jar包有空再一并上传
