Two-stage structure aware image inpainting based on generative adversarial networks

In recent years, the image inpainting technology based on deep learning has made remarkable progress, which can better complete the complex image inpainting task compared with traditional methods. However, most of the existing methods can not generate reasonable structure and fine texture details at the same time. To solve this problem, in this paper we propose a two-stage image inpainting method with structure awareness based on Generative Adversarial Networks, which divides the inpainting process into two sub tasks, namely, image structure generation and image content generation. In the former stage, the network generates the structural information of the missing area; while in the latter stage, the network uses this structural information as a prior, and combines the existing texture and color information to complete the image. Extensive experiments are conducted to evaluate the performance of our proposed method on Places2, CelebA and Paris Streetview datasets. The experimental results show the superior performance of the proposed method compared with other state-of-the-art methods qualitatively and quantitatively.
