AI人脸识别+图像识别【文末源码分享】
AI的发展在最近几年如火如荼，工资待遇也是水涨船高，应用的前景也是非常广阔，去年火起来的人脸识别，今年全国遍地开花。看了下百度的AI，还免费了，效果也是越来越好，活体检测这个算法更是做的吊炸天（只需要传一张图片就能判断图片中的人是翻拍的照片非活体），牛逼的一塌糊涂，我反正是跪了。百度AI在未来的国内AI市场中，不是第一就是第二，而且会持续保持至少十年。
文章图片
1:可识别身份证正面信息+背面信息
2:可识别银行卡信息
3:可识别驾驶证+行驶证信息
4:可进行人脸识别,人脸比对,活体检测
5:可设置请求地址+用户密钥+应用密钥
6:直接传入图片即可,信号返回,毫秒级极速响应
7:通用Qt4-Qt5,windows linux 嵌入式linux
【AI人脸识别+图像识别【文末源码分享】】下面看一下演示效果
