摘要:

偏振图像之间的逐像素操作对于处理偏振信息是重要的。由于缺乏这样的操作,极化信息不能充分利用卷积神经网络(CNN)。在本文中,提出了一种新的端到端的CNN框架的偏振视觉任务,使网络充分利用偏振图像。该框架由两个子网络组成:极化参数构造网络(PPCN)和任务网络。PPCN以具有1x1卷积核的CNN形式在图像之间实现逐像素操作。它以原始偏振图像为输入,将偏振参数图像输出到任务网络,完成视觉任务。通过一起训练,PPCN可以学习为任务网络和数据集提供最合适的偏振参数图像。以更快的R-CNN作为任务网络,实验结果表明,与现有方法相比,该框架在目标检测任务中获得了更高的平均精度(mAP)

英文摘要:

Pixel-wise operations between polarimetric images are important for processing polarization information. For the lack of such operations, the polarization information cannot be fully utilized in convolutional neural network(CNN). In this paper, a novel end-to-end CNN framework for polarization vision tasks is proposed, which enables the networks to take full advantage of polarimetric images. The framework consists of two sub-networks: a polarization-parameter-constructing network (PPCN) and a task network. PPCN implements pixel-wise operations between images in the CNN form with 1x1 convolution kernels. It takes raw polarimetric images as input, and outputs polarization-parametric images to task network so as to complete a vison task. By training together, the PPCN can learn to provide the most suitable polarization-parametric images for the task network and the dataset. Taking faster R-CNN as task network, the experimental results show that compared with existing methods, the proposed framework achieves much higher mean-average-precision (mAP) in object detection task
