脸部视频可以精确透露出你的心跳速度。MIT研究人员 Guha Balakrishnan和同时开发出一套系统，通过分析血液流动导致的细微头部运动去测量心跳。这种微小的运动肉眼无法识别。系统首先利用面部识别技术从视频中识别出脸，然后在嘴和鼻子附近随机选择数百个点，逐帧跟踪点的运动，消除呼吸和位置变化引起的移动，得到心跳的频率范围。这项技术可用于监视婴儿和老年人的心态，判断心脏是否存在危险。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
