Wavefront-Constrained Passive Obscured Object Detection

  • 基于波前传播的物理驱动网络,模拟光在介质中传播过程
  • 在四个真实数据集上均超越现有方法,精度与稳定性更优
  • 适合光学成像、低信噪环境下的隐蔽物体感知任务

由于多重散射和介质引起的扰动,从视场外微弱光模式中准确定位和分割被遮挡物体极具挑战。现有基于实值建模或局部卷积的方法难以捕捉相干光传播的底层物理机制,在低信噪比条件下常收敛到非物理解,严重影响观测稳定性与可靠性。为此,我们提出一种新型物理驱动的波前传播补偿网络(WavePCNet),通过三相波前复数传播重投影(TriWCP)引入复振幅传递算子,精确约束相干传播行为,并结合动量记忆机制有效抑制扰动累积。此外,引入高频跨层补偿增强模块,构建具有多尺度感受野的频率选择性路径,动态建模层间结构一致性,进一步提升复杂环境下的鲁棒性与可解释性。在四个物理采集数据集上的大量实验表明,WavePCNet 在准确性和鲁棒性上均持续优于当前最优方法。

原文摘要 · Abstract (English)

Accurately localizing and segmenting obscured objects from faint light patterns beyond the field of view is highly challenging due to multiple scattering and medium-induced perturbations. Most existing methods, based on real-valued modeling or local convolutional operations, are inadequate for capturing the underlying physics of coherent light propagation. Moreover, under low signal-to-noise conditions, these methods often converge to non-physical solutions, severely compromising the stability and reliability of the observation. To address these challenges, we propose a novel physics-driven Wavefront Propagating Compensation Network (WavePCNet) to simulate wavefront propagation and enhance the perception of obscured objects. This WavePCNet integrates the Tri-Phase Wavefront Complex-Propagation Reprojection (TriWCP) to incorporate complex amplitude transfer operators to precisely constrain coherent propagation behavior, along with a momentum memory mechanism to effectively suppress the accumulation of perturbations. Additionally, a High-frequency Cross-layer Compensation Enhancement is introduced to construct frequency-selective pathways with multi-scale receptive fields and dynamically model structural consistency across layers, further boosting the model's robustness and interpretability under complex environmental conditions. Extensive experiments conducted on four physically collected datasets demonstrate that WavePCNet consistently outperforms state-of-the-art methods across both accuracy and robustness.
