Abstract

In this study, a co-designed optoelectronic framework for edge detection was proposed. Four optical filters Vortex phase filter (VPF), Gaussian vortex filter (GVF), High-pass filter (HPF) and Laguerre-Gaussian vortex filter (LGF)—serve as spatial preprocessing modules in a 4f-system, enhancing edge signals optically, while electronic thresholding modules binarize outputs for decision-making. Quantitative comparisons on BSDS500 under noise-free and multiplicative noise (variance=0.02) conditions evaluate both per-image (OIS) and dataset-scale (ODS) optimization. Using the Canny operator as a reference, the results provide recommendations for optical filters with robust edge detection capabilities and noise resilience.

光电计算中光学边缘检测滤波器的性能权衡

在这项研究中，提出了一个共同设计的光电边缘检测框架。四个光学滤波器涡旋相位滤波器（VPF）、高斯涡旋滤波器（GVF）、高通滤波器（HPF）和拉盖尔-高斯涡旋滤波器（LGF）在4f系统中作为空间预处理模块，从光学上增强边缘信号，而电子阈值模块对输出进行二值化以供决策。在无噪声和乘性噪声（方差=0.02）条件下对BSDS500进行定量比较，评估单图像（OIS）和数据集尺度（ODS）优化。以Canny算子为参考，给出了具有鲁棒边缘检测能力和抗噪声能力的光学滤波器的建议。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
