中国网娱乐7月21日讯 2017年中国人工智能大会即将召开,人工智能这一话题再次成为社会关注的热点。近几年,科学界一直在人工智能上寻求突破,尤其是在人脸识别寻人方面,AI技术是否能够通过高科技手段,在寻找走失儿童等社会公益领域发挥作用,成为焦点话题。值得一提的是,目前中国科学院自动化研究所已发明出人工智能机器人,在人脸识别率上接近百分百,并投入到实际应用中,成功帮助公安部门寻回失散40年的双胞胎兄弟。据悉,这台寻人机器人也将在央视综合频道本周日晚黄金档播出的《加油!向未来》第二季节目中首度亮相。

精准度高达99% AI人工识别机器人亮相央视

据了解,这台名为“小加”的人工智能机器人是由中国科学院自动化研究所模式识别国家重点实验室研究员王金桥科研团队研发,其人脸识别的精准度已接近99%——在身份证与现场照比对方面,在百万分之一的虚警率下,“小加”人脸验证准确率达到99%以上。在动态监控人脸识别方面,在十万分之一的虚警率下,“小加”人脸识别准确率达到85%。王金桥表示,“小加”的人脸识别采用一种基于深度学习的低功耗深度耦合神经网络算法,能够同时捕捉到人脸的全局结构特征和局部细微差异,从而学习到一个人的个性化人脸特征。当前市场上的算法通常难以克服姿态和光照变化带来的影响,为了解决这一历史性的难题,我们通过引入三维人脸模型,提出了一种三维形变神经网络,能够实现高精度中远距离的人脸动态识别。
