compressed sensing
The passage:One area of his research — compressed sensing — could have real-world use. Digital cameras use millions of sensors to record an image, and then a computer chip in the camera compresses the data.
“Compressed sensing is a different strategy,” Dr. Tao said. “You also compress the data, but you try to do it in a very dumb way, one that doesn’t require much computer power at the sensor end.”
参考答案:段落：他的研究领域－－压缩传感－－可以应用到实际当中。数码相机用数以万计的传感器来记录一个画面，然后相机中的一个电脑芯片把该数据压缩。
“压缩传感采用不同的办法”，桃博士说道。“你也压缩数据，但是是通过一种软方式，这种方式不需要在传感器末端应用的电脑技术。”
