Metavision 传感器的像素独立性和智能功耗模式架构实现了新的功率效率水平,超低功耗模式下低至36uW和典型模式下低至3mW。 底层设计隐私保护 事件,而不是图像 Prophesee基于事件的Metavision传感器不捕获图像,而是捕获事件,是由单个像素驱动的稀疏异步数据。同时,由于只获取运动信息,在传感器层面忽略了静态场景背景信息。
Event-based Vision Sensors (EVS) help alleviate this issue by only sending data from pixels that have detected a change in intensity. This allows them to minimize the volume of data that is transmitted over the sensor’s data bus while minimizing the processing resources need to analyze the im...
Event-based sensors enable super-resolution single-molecule localization microscopy with comparable quality and resolution to traditional scientific cameras, while also overcoming the limitations of high-density imaging.Cabriel ClémentUniversité PSLMonfort Tual...
Here we present a new approach to SMLM data acquisition and processing based on an affordable event-based sensor. This type of sensor reacts to changes in light intensity, rather than integrating photons during the exposure time of each frame. Each pixel works independently and returns a signal...

目前被广泛应用的事件相机可大致分成3类:动态视觉传感器(DVS)、基于异步时间的图像传感器(ATIS)、动态主动像素视觉传感器(DAVIS,Dynamic and Active Pixel Vision Sensor)。DVS是最基本的也是最先发展的一种事件相机。ATIS像素结构分成两个部分(A和B),包含两个感光器,能够在提供事件信息的同时还能提供一定灰度信息的需...
