论文摘要
面向平面或微电网图像极化计使我们能够一次拍摄一组极化图像。由于偏振仪由配备单色或颜色极化滤光片阵列（MPFA或CPFA）组成的图像传感器，因此插入插入缺失像素值的演示过程在获得高质量极化图像中起着至关重要的作用。在本文中，我们提出了一种基于边缘感知的残留插值（EARI）的新型MPFA Demosaicking方法，并将其扩展到CPFA Demosaicking。 EARI的关键是一种新的边缘检测器，用于生成用于插值缺失像素值的有效指南图像。我们还提出了一个新建的完整颜色偏振图像数据集，该图像数据集使用3-CCD摄像头和旋转偏振器捕获。使用数据集，我们在实验上证明了我们的基于EARI的方法在MPFA和CPFA Demosaicking中的现有方法优于现有方法。
A division-of-focal-plane or microgrid image polarimeter enables us to acquire a set of polarization images in one shot. Since the polarimeter consists of an image sensor equipped with a monochrome or color polarization filter array (MPFA or CPFA), the demosaicking process to interpolate missing pixel values plays a crucial role in obtaining high-quality polarization images. In this paper, we propose a novel MPFA demosaicking method based on edge-aware residual interpolation (EARI) and also extend it to CPFA demosaicking. The key of EARI is a new edge detector for generating an effective guide image used to interpolate the missing pixel values. We also present a newly constructed full color-polarization image dataset captured using a 3-CCD camera and a rotating polarizer. Using the dataset, we experimentally demonstrate that our EARI-based method outperforms existing methods in MPFA and CPFA demosaicking.
