The layout guidance, which specifies the pixel-wise object distribution, is beneficial to preserving the object boundaries in image inpainting while not hurting models generalization capability. We aim to design an efficient and robust layout-guided image inpainting method for mobile use, which can achieve the robustness in presence of the mixed scenes where objects with the delicate shape reside next to the hole. Our method is made up of two sub-models, which restore the pixel-information for the hole from coarse to fine, and support each other to overcome the practical challenges encountered when making the whole method lightweight. The layout mask guides the two sub-models, which thus enables the robustness of our method in mixed scenes. We demonstrate the efficiency and robustness of our method via both the experiments and a mobile demo.
