Text-Guided Image Inpainting

Abstract

Given a partially masked image, image inpainting aims to complete the missing region and output a plausible image. Most existing image inpainting methods complete the missing region by expanding or borrowing information from the surrounding source region, which work well when the original content in the missing region is similar to the surrounding source region. Unsatisfactory results will be generated if there is no sufficient contextual information can be referenced from source region. Besides, the inpainting results should be diverse and this kind of diversity should be controllable. Based on these observations, we propose a new inpainting problem that introduces text as a kind of guidance to direct and control the inpainting process. The main difference between this problem and previous works is that we need ensure the result to be consistent with not only the source region but also the textual guidance during inpainting. By this way, we want to avoid the unreasonable completion and meanwhile make it controllable. We propose a progressively coarse-To-fine cross-modal generative network and adopt the text-image-Text training schema to generate visually consistent and semantically coherent images. Extensive quantitative and qualitative experiments on two public datasets with captions demonstrate the effectiveness of our method.
