The novel camera architecture facilitates the development of machine vision. Instead of capturing frame sequences in the temporal domain as traditional video cameras, FourierCam directly measures the pixel-wise temporal spectrum of the video in a single shot through optical coding. Compared to the classic video cameras and time-frequency transformation pipeline, this programmable frequency-domain sampling strategy has an attractive combination of characteristics for low detection bandwidth, low computational burden, and low data volume. Based on the various temporal filter kernel designed by FourierCam, we demonstrated a series of exciting machine vision functions, such as video compression, background subtraction, object extraction, and trajectory tracking.

FourierCam：一次拍摄视频频谱的摄像机

新颖的相机架构促进了机器视觉的发展。FourierCam并没有像传统的摄像机那样在时域中捕获帧序列，而是通过光学编码直接测量单次拍摄中视频的像素级时域频谱。与传统的摄像机和时频转换流水线相比，这种可编程的频域采样策略具有低带宽，低计算量和低数据量等特点的吸引人的组合。基于FourierCam设计的各种时间滤波器内核，我们演示了一系列令人兴奋的机器视觉功能，例如视频压缩，背景减法，对象提取和轨迹跟踪。
