快速可靠的运动检测对动态环境中运行的机器视觉和自主系统至关重要。本文将新兴的事件传感与生物结构化神经计算相结合,构建了一种高效的视觉运动检测计算范式。所提框架基于近期发展的仿果蝇神经网络,模拟视叶中的运动处理回路。由于其前馈且无需训练的架构,该神经模型仅需少量可解释参数,非常适合实时嵌入式实现。事件相机通过异步传输亮度变化事件,实现低延迟、低功耗和高动态范围感知。然而,在低光条件下,事件噪声(包括时间噪声和结漏电引起的活动)会降低其性能。此外,事件视觉表示与生物启发神经处理的有效融合仍待探索。为此,我们提出一种事件驱动的计算框架,结合时间表面编码进行前端事件表征,并采用仿果蝇视叶神经网络进行前景运动方向估计。进一步引入自下而上的注意力机制,以抑制背景运动并增强前景目标显著性。该方法在真实世界车载数据集上进行了评估,并与基于帧的基线模型及优化方法对比。实验结果表明,该框架有效结合了事件视觉的时间优势与生物启发神经处理的高效性和可解释性。

原文摘要 · Abstract (English)

Fast and reliable motion detection is essential for machine vision and autonomous systems operating in dynamic environments. This work integrates emerging event-based sensing with biologically structured neural computation to establish an efficient computational paradigm for visual motion detection. The proposed framework is built upon a recently developed fly-inspired neural network that emulates motion-processing circuits in the optic lobe. Owing to its feed-forward and training-free architecture, the neural model requires only a small number of interpretable parameters and is well suited for real-time embedded implementation. Event cameras provide low-latency, low-power, and high-dynamic-range visual sensing by asynchronously transmitting brightness-change events. However, their performance can be degraded by event noise, including temporal noise and junction-leakage-induced activity, particularly under low-light conditions. Moreover, effective integration between event-based visual representations and biologically inspired neural processing remains under-explored. To address these challenges, we propose an event-driven computational framework that combines time-surface encoding for front-end event representation with a fly optic-lobe-inspired neural network for foreground motion-direction estimation. A bottom-up attention mechanism is further incorporated to suppress background motion and enhance the saliency of foreground targets. The proposed method is evaluated on real-world ground-vehicle datasets and compared with a baseline frame-based model and an optimization-based approach. Experimental results demonstrate that the framework effectively combines the temporal advantages of event-driven vision with the efficiency and interpretability of bio-inspired neural processing.
