In this paper, we propose a novel controllable text-to-image generative adversarial network (ControlGAN), which can effectively synthesise high-quality images and also control parts of the image generation according to natural language descriptions. To achieve this, we introduce a word-level spatial and channel-wise attention-driven generator that can disentangle different visual attributes, and allow the model to focus on generating and manipulating subregions corresponding to the most relevant words. Also, a word-level discriminator is proposed to provide fine-grained supervisory feedback by correlating words with image regions, facilitating training an effective generator which is able to manipulate specific visual attributes without affecting the generation of other contents. Furthermore, perceptual loss is adopted to reduce the randomness involved in the image generation, and to encourage the generator to manipulate specific attributes required in the modified text. Extensive experiments on benchmark datasets demonstrate that our method outperforms existing state of the art, and is able to effectively manipulate synthetic images using natural language descriptions.

该论文提出了一种新颖的可控文本到图像生成对抗网络(ControlGAN)，它能够有效地合成高质量图像并根据自然语言描述控制图像的生成。该方法采用词级空间和通道注意力机制对不同的视觉属性进行分离，并通过词级鉴别器提供细粒度的监督反馈，使生成器能够对特定的视觉属性进行操作。通过大量的实验证明，我们的方法优于现有的最先进技术，并能够通过自然语言描述有效地操作合成图像。
