复杂背景的目标识别是物联网边缘感知体系中很重要的任务,而红外偏振图像在安防,伪装检测领域展现出优越的目标背景对比度。然而,由于成像系统计算速度慢以及传感器硬件缺陷问题,长波红外焦平面分割偏振成像系统在实际应用中难以高效获取高质量的图像,阻碍下游检测等任务的精度。为此,提出一种基于空频域协同的轻量级红外偏振图像联合去噪与去马赛克方法,该方法通过构建三阶段学习网络,在保证低计算复杂度的同时提升偏振图像重建质量。所设计的双域交互去噪模块充分利用频域信息的统计性特征,有效抑制噪声并保留偏振特性;同时,在粗糙去马赛克之后引入轻量化精细重建模块,通过深度分组卷积压缩模型参数量并提升重建性能。实验结果表明,所提方法在 IR-DoT 与 IR-DoFP 数据集上在保持低计算开销的前提下取得了优于现有方法的重建效果,为物联网边缘终端提供了一种低功耗、高质量的感知数据预处理方案。
Object recognition in complex scenes is an important task in the Internet of Things (IoT) based edge perception systems. Infrared polarization images show superior foreground–background contrast in security monitoring and camouflage detection. However
due to the limited hardware resources of imaging systems
it is difficult for long-wave infrared division-of-focal-plane (DoFP) polarization imaging systems to achieve high-quality images in practical applications
which adversely affects edge perception performance. To this end
a lightweight joint denoising and demosaicking network for infrared polarization images is developed via spatial-frequency collaborative learning. The proposed method employs a three-stage learning network to enhance the quality of polarization image reconstruction while maintaining low computational complexity. The dual-domain interactive denoising block leverages the statistical properties of the frequency domain to suppress noise while preserving polarization features. After coarse demosaicking
a lightweight fine reconstruction module is adopted to generate the final results. Depthwise grouped convolutions are used to reduce model parameter count and improve reconstruction quality. Extensive experiments are performed on the IR-DoT and IR-DoFP datasets. The results show that the proposed method achieves superior performance compared with other leading approaches while maintaining low computational overhead
making it a low-power
high-quality data preprocessing approach for IoT-based edge devices.
