Removing the undesired reflections from images taken through the glass is of
broad application to various computer vision tasks. Non-learning based methods
utilize different handcrafted priors such as the separable sparse gradients
caused by different levels of blurs, which often fail due to their limited
description capability to the properties of real-world reflections. In this
paper, we propose the Concurrent Reflection Removal Network (CRRN) to tackle
this problem in a unified framework. Our proposed network integrates image
appearance information and multi-scale gradient information with human
perception inspired loss function, and is trained on a new dataset with 3250
reflection images taken under diverse real-world scenes. Extensive experiments
on a public benchmark dataset show that the proposed method performs favorably
against state-of-the-art methods.

本文提出了一种名为 Concurrent Reflection Removal Network (CRRN) 的反射去除网络，该网络利用图像外观信息和多尺度梯度信息提出了一种新的、基于人类感知的损失函数，并应用于新的 3250 张真实世界场景下的反射图像数据集上进行了训练及与基准数据集的对比实验，结果表明该方法胜过了同类先进方法。
