We present a photodetector sensor that is able to perform preprocessing operations on the focal plane. Each pixel can be connected with any of its neighbors in order to implement detection zones defined by software. The output current of the sensor is a customizable weighted sum of the currents sourced at the defined detection zones. This characteristic leads to applications related to pattern matching. Two examples are shown in our work: one is related to speckle correlation for real-time vibration detection, and the other one is an alternative image recording method that is the first step to an on-hardware compressed sensing technique.

具有像素间可编程互连的面向模式匹配的光电探测器图像传感器

我们提出了一种能够在焦平面上执行预处理操作的光电探测器传感器。每个像素都可以与其任何相邻像素连接，以实现由软件定义的检测区域。传感器的输出电流是来自定义检测区域的电流的可定制加权总和。这一特性导致了与模式匹配相关的应用。我们的工作中展示了两个例子：一个与实时振动检测的散斑相关性有关，另一个是替代的图像记录方法，它是硬件压缩传感技术的第一步。
