Recently, there have been several promising methods to generate realistic imagery from deep convolutional networks. These methods sidestep the traditional computer graphics rendering pipeline and instead generate imagery at the pixel level by learning from large collections of photos (e.g. faces or bedrooms). However, these methods are of limited utility because it is difficult for a user to control what the network produces. In this paper, we propose a deep adversarial image synthesis architecture that is conditioned on coarse sketches and sparse color strokes to generate realistic cars, bedrooms, or faces. We demonstrate a sketch based image synthesis system which allows users to 'scribble' over the sketch to indicate preferred color for objects. Our network can then generate convincing images that satisfy both the color and the sketch constraints of user. The network is feed-forward which allows users to see the effect of their edits in real time. We compare to recent work on sketch to image synthesis and show that our approach can generate more realistic, more diverse, and more controllable outputs. The architecture is also effective at user-guided colorization of grayscale images.

本文提出了一种基于深度对抗图像合成框架，结合草图轮廓和稀疏颜色笔画生成逼真的汽车、卧室或人脸。我们展示了一个基于草图的图像合成系统，允许用户在草图上涂鸦以指示所需对象的首选颜色。该网络是前向的，可以实时看到用户编辑的效果。与最近关于草图到图像合成的研究进行了比较，表明我们的方法可以生成更逼真、更多样和更可控的输出，并且对于灰度图像的用户引导上色也很有效。
