摘要:

不成对训练可能是基于快速深度学习的重影成像的唯一选择,其中获得每个低SNR重影图像的高信噪比(SNR)图像副本实际上可能是耗时且具有挑战性的。本文探讨了深度学习在缺乏成对训练图像时利用计算重影成像的能力。本文提出的深度学习方法通过使用约束Wasserstein生成对抗网络从微弱和匆忙拍摄的鬼像重建高SNR图像来实现快速鬼像成像。在所提出的方法中,目标函数被正则化,以执行生成忠实的和相关的高信噪比图像的幽灵副本。这种正则化测量重建图像和阴影网络生成的低噪声流形中的微弱鬼像之间的距离。约束网络的性能被证明是特别重要的鬼图像与低信噪比。所提出的流水线能够从具有SNR值不一定等于训练集的SNR的鬼像重建高质量的图像。

英文摘要:

The unpaired training can be the only option available for fast deep learning-based ghost imaging, where obtaining a high signal-to-noise ratio (SNR) image copy of each low SNR ghost image could be practically time-consuming and challenging. This paper explores the capabilities of deep learning to leverage computational ghost imaging when there is a lack of paired training images. The deep learning approach proposed here enables fast ghost imaging through reconstruction of high SNR images from faint and hastily shot ghost images using a constrained Wasserstein generative adversarial network. In the proposed approach, the objective function is regularized to enforce the generation of faithful and relevant high SNR images to the ghost copies. This regularization measures the distance between reconstructed images and the faint ghost images in a low-noise manifold generated by a shadow network. The performance of the constrained network is shown to be particularly important for ghost images with low SNR. The proposed pipeline is able to reconstruct high-quality images from the ghost images with SNR values not necessarily equal to the SNR of the training set.
