摘要:

使用深度卷积网络执行图像操作的系统已经实现了显着的真实感。感知损失和基于对抗性鉴别器的损失是这些进步背后的两类主要学习目标。在这项工作中,我们将展示如何将这两个想法以原则性和非添加性的方式结合起来,用于未对齐的图像翻译任务。这是通过生成对抗学习框架内的一个特殊的网络架构来实现的。我们称之为感知分类器的新架构将预先训练的深度分类网络的卷积部分嵌入到感知分类器网络中。由此产生的架构可以在未对齐的图像数据集上进行训练,同时受益于感知损失的鲁棒性和效率。我们展示了新架构的优点,在一系列的定性和定量比较与基线方法和国家的最先进的框架不对齐的图像翻译。

英文摘要:

Systems that perform image manipulation using deep convolutional networks have achieved remarkable realism. Perceptual losses and losses based on adversarial discriminators are the two main classes of learning objectives behind these advances. In this work, we show how these two ideas can be combined in a principled and non-additive manner for unaligned image translation tasks. This is accomplished through a special architecture of the discriminator network inside generative adversarial learning framework. The new architecture, that we call a perceptual discriminator, embeds the convolutional parts of a pre-trained deep classification network inside the discriminator network. The resulting architecture can be trained on unaligned image datasets while benefiting from the robustness and efficiency of perceptual losses. We demonstrate the merits of the new architecture in a series of qualitative and quantitative comparisons with baseline approaches and state-of-the-art frameworks for unaligned image translation.
