论文摘要
场景中光的极化信息对于各种图像处理和计算机视觉任务很有价值。面向平面偏光仪是一种有前途的方法，是一次拍摄不同方向的极化图像，而它需要颜色极化的表现。在本文中，我们提出了一个两步的颜色偏振化学网络〜（TCPDNET），该网络由两个颜色的表演和极化演示组成。我们还引入了YCBCR颜色空间中的重建损失，以提高TCPDNET的性能。实验比较表明，TCPDNET在极化图像的图像质量和Stokes参数的准确性方面优于现有方法。
Polarization information of light in a scene is valuable for various image processing and computer vision tasks. A division-of-focal-plane polarimeter is a promising approach to capture the polarization images of different orientations in one shot, while it requires color-polarization demosaicking. In this paper, we propose a two-step color-polarization demosaicking network~(TCPDNet), which consists of two sub-tasks of color demosaicking and polarization demosaicking. We also introduce a reconstruction loss in the YCbCr color space to improve the performance of TCPDNet. Experimental comparisons demonstrate that TCPDNet outperforms existing methods in terms of the image quality of polarization images and the accuracy of Stokes parameters.
