基于百度AI实现文字和图像敏感内容审核
前言百度AI是指百度公司的人工智能技术全称。它采用深度学习技术，包括自然语言处理、语音识别、计算机视觉、知识图谱等，可应用于各个领域如互联网、医疗、金融、教育、汽车、物流等。百度AI的发展将帮助人类更好地理解世界和提高生活品质，接下来就通过一个小案例演示实现百度AI在文字和图像敏感审核应用。
项目准备
1.注册并登录百度智能云账号

项目搭建与配置
1.创建Winform客户端
[*]项目结构

2.Nuget安装BaiduAI包
NuGet\Install-Package Baidu.AI -Version 4.15.13
3.添加应用Key配置
文件：BaseConfig.json配置申请的应用信息
{
"BaiduAI": {
"AppId": "xxxx",//配置自己申请的
"ApiKey": "xxxx",//配置自己申请的
"SecretKey": "xxxx"//配置自己申请的
}
}项目代码实现
贴出实现功能的核心代码，整个项目的源码文末尾提供获取方式。
