摘要：的發(fā)展在最近幾年如火如荼，工資待遇也是水漲船高，應(yīng)用的前景也是非常廣闊，去年火起來(lái)的人臉識(shí)別，今年全國(guó)遍地開(kāi)花。百度在未來(lái)的國(guó)內(nèi)市場(chǎng)中，不是第一就是第二，而且會(huì)持續(xù)保持至少十年。

AI的發(fā)展在最近幾年如火如荼，工資待遇也是水漲船高，應(yīng)用的前景也是非常廣闊，去年火起來(lái)的人臉識(shí)別，今年全國(guó)遍地開(kāi)花?？戳讼掳俣鹊腁I，還免費(fèi)了，效果也是越來(lái)越好，活體檢測(cè)這個(gè)算法更是做的吊炸天（只需要傳一張圖片就能判斷圖片中的人是翻拍的照片非活體），牛逼的一塌糊涂，我反正是跪了。百度AI在未來(lái)的國(guó)內(nèi)AI市場(chǎng)中，不是第一就是第二，而且會(huì)持續(xù)保持至少十年。

1:可識(shí)別身份證正面信息+背面信息

2:可識(shí)別銀行卡信息

3:可識(shí)別駕駛證+行駛證信息

4:可進(jìn)行人臉識(shí)別,人臉比對(duì),活體檢測(cè)

5:可設(shè)置請(qǐng)求地址+用戶密鑰+應(yīng)用密鑰

6:直接傳入圖片即可,信號(hào)返回,毫秒級(jí)極速響應(yīng)

7:通用Qt4-Qt5,windows linux 嵌入式linux
下面看一下演示效果

當(dāng)然下面這個(gè)是識(shí)別不了的
