人脸识别App集合

开源人脸识别软件，到目前为止还没有什么精度比较好的。
OpenCV里面的人脸检测及其相关的haar detector还是蛮不错的，但想搞靠谱实用还是的自己重新train。
人脸识别最好的几家公司都在07年的frvt（google收购的NV参与了这届，综合性能第一）和后来的10年的mbe（google收购的pittpatt参加了这届，性能一般，但他们的人脸检测、姿态估计似乎很好，cmu的人马，专利不少）网站上了。看看就知道最好的人脸识别技术能达到什么程度了

开源的人脸识别没有一个靠谱的。OpenCV等自带的很弱，face++等是服务接口，不是开源代码。

这两年随着深度学习的流行，人脸识别技术提高一大截，主要是归一化和特征提取部分。虽然很多机构和公司都发了准确率刷榜文章，但没有一家release出源码和模型。

以前常用的ASM、Gabor、LBP等相比落后很多了。所以如果是三年前的技术，基本也落后了。

所以结论是，想要有靠谱的技术，只能自己做。人脸检测、特征点定位归一化、人脸特征与识别模型，每一块都需要至少一个月时间，不熟悉的话，几个月也正常。

国际人脸识别评估集LFW榜， face++ 99.5% , 商汤 99.53% ， 腾讯 99.65% , 百度 99.77%，中科奥森 99.77% , 中科云从 99.5%， 颜鉴99.64%，北京飞搜科技 99.4% ,宇泛智能 99%，

这个是在ColorReco官网上测的人脸比对

劲爆！实测目前最火的人脸识别技术(百度、腾讯、微软、旷视、虹软)

最近国内“AI”圈儿里，最热的大概就是百度的阿波罗和阿里的无人售卖了吧，商汤成为资本的宠儿，一向低调的虹软竟然发布了免费的人脸识别技术，一派热火朝天。

对这个圈子稍微了解点的都知道，最近两年AI真的是备受恩宠啊，各种研究机构，创业公司想着法儿往圈子里挤，都想分一杯羹，拿风投，抢融资，笔者也一直在跟踪业内人脸识别技术，个人做了一个评测。

现在的人脸识别技术的公司实在太多了，这一次的评测，本人只挑选了业内比较知名的几家人脸识别技术公司，百度，微软，腾讯就不提了，三大巨头，商汤科技，旷视科技，上海依图和云从科技都是近两年异军突起的新兴创业公司，发展迅猛，我挑选了其中竞争力比较强的旷视科技进行评测(本来是想把商汤的技术也找来比较下，结果搜了半天没找到可测试的免费版本，有点儿小遗憾)，另外比较特殊的是虹软公司，之前的评测就很想加他们的，可惜那时候他们没开放技术，这一次刚好他们发布了免费的人脸识别SDK，在计算机视觉技术上他们属于高富帅行列。

接口API实现方式，数据处理方式以及调用限制

除了虹软外，其他4家都是直接提供云平台API接口。云平台API接口调用虽然接入应用相对比较简单，但在使用上会受制于网络稳定性，用户体验会有一定的影响;而且高私密性的人脸照片被传到别人家的公有云服务器，存在泄漏的风险，如果是企业用户，对隐私这种事情，就比较敏感了，我猜想虹软选择开放本地离线SDK引擎，大概也是出于大量客户保护数据安全这方面的要求吧。这样一来就可以不受网络影响，自己掌控人脸照片及相关企业信息，在用户体验和数据安全方面都有很大的保障。只是，如果要使用本地离线SDK引擎接入应用应该会比直接使用云平台API难度大，不过对于久经沙场的程序猿们来说这都不是事儿，如果有Sample code的话，学习使用起来就更容易了。

人脸检测识别功能

从功能来看，人脸检测和人脸识别大家都支持，但虹软还支持人脸跟踪，大概是由于虹软提供的是离线SDK，可以实现人脸跟踪功能，因为本地的话，对网络和流量的要求就不会有云平台那么高;当然如果产品自建云或者在客户那自组网的情况下，也是非常好用的，这样场景确实蛮多的。这个离线版本在虹软的官网上也有重点介绍，应该是他的亮点。

人脸识别技术能力

为了真实评测各家公司的人脸识别技术能力，笔者之前就花了比较多的时间对各家的API接口做了集成，拿100张照片(照片进行了挑选，包括了我们关注的常用场景和多个人脸的情况)进行了对比，加上这次虹软的。

为了公平起见，我是在同等误识率(0%)的情况下获取的识别率。

从测试结果来看，就人脸的识别能力来看，虹软是领先于其他几家公司的，在复杂光线下的处理，百度略胜一筹，猜测或许虹软用的是非大企业商用的版本，或许是不是有所保留。然后是旷视，微软。

综合看下来，个人着实吃了一惊。没想到这次免费发布的虹软人脸识别SDK居然表现如此上佳。虹软果然有货!SDK在商业模式上，有明显优势，在技术上也比其他家稍强，而且能适应很多的应用场景，比如人脸认证、门禁考勤、智能家居/机器人、安防监控之类。恐怕几家大佬要坐不住了。
