摘要:

我们提出了一个基于深度学习和定制粉红噪声散斑图案的计算鬼成像框架。本文中的深度神经网络可以学习传感模型并提高图像重建质量,仅通过模拟来训练。为了证明我们工作中的亚奈奎斯特水平,在不同噪声条件下的多个采样率下比较了传统计算鬼成像结果、使用白噪声和粉红噪声通过深度学习重建的成像结果。我们表明,该方案可以提供高质量的图像,采样率为0.8%,即使对象是在训练数据集之外,它是鲁棒的噪声环境。该方法对于各种应用都是极好的,特别是那些需要低采样率、快速重构效率或经历强噪声干扰的应用。

英文摘要:

We present a framework for computational ghost imaging based on deep learning and customized pink noise speckle patterns. The deep neural network in this work, which can learn the sensing model and enhance image reconstruction quality, is trained merely by simulation. To demonstrate the sub-Nyquist level in our work, the conventional computational ghost imaging results, reconstructed imaging results using white noise and pink noise via deep learning are compared under multiple sampling rates at different noise conditions. We show that the proposed scheme can provide high-quality images with a sampling rate of 0.8% even when the object is outside the training dataset, and it is robust to noisy environments. This method is excellent for various applications, particularly those that require a low sampling rate, fast reconstruction efficiency, or experience strong noise interference.
