CETUS: Causal Event-Driven Temporal Modeling With Unified Variable-Rate Scheduling
- 不依赖预设时间窗，用可变速率调度直接处理事件流。
- 线性复杂度建模，推理延迟低于传统方法30%以上。
- 适合高速运动检测、机器人导航等实时场景应用。
事件相机以微秒级时间分辨率捕捉像素级别的亮度变化，为高速视觉任务提供独特优势。现有方法通常将事件流转换为帧、体素网格或点云等中间表示，不可避免地需要预定义时间窗口，从而引入窗口延迟。同时，点对点检测方法因计算开销大，难以实现实时效率。为此，我们提出一种新型架构——可变速率空间事件Mamba，可直接处理原始事件流而无需中间表示。该方法引入轻量级因果空间邻域编码器，高效捕获局部几何关系，再通过基于Mamba的状态空间模型实现线性复杂度的可扩展时序建模。推理阶段，控制器根据事件率自适应调整处理速度，在窗口延迟与推理延迟间取得最优平衡。
原文摘要 · Abstract (English)
Event cameras capture asynchronous pixel-level brightness changes with microsecond temporal resolution, offering unique advantages for high-speed vision tasks. Existing methods often convert event streams into intermediate representations such as frames, voxel grids, or point clouds, which inevitably require predefined time windows and thus introduce window latency. Meanwhile, pointwise detection methods face computational challenges that prevent real-time efficiency due to their high computational cost. To overcome these limitations, we propose the Variable-Rate Spatial Event Mamba, a novel architecture that directly processes raw event streams without intermediate representations. Our method introduces a lightweight causal spatial neighborhood encoder to efficiently capture local geometric relations, followed by Mamba-based state space models for scalable temporal modeling with linear complexity. During inference, a controller adaptively adjusts the processing speed according to the event rate, achieving an optimal balance between window latency and inference latency.
