Bargainnet: Background-Guided Domain Translation for Image Harmonization

Given a composite image with inharmonious foreground and background, image harmonization aims to adjust the foreground to make it compatible with the background. Previous image harmonization methods mainly focus on learning the mapping from composite image to real image, while ignoring the crucial guidance role that background plays. In this work, we formulate image harmonization task as background-guided domain translation. Specifically, we use a domain code extractor to capture the background domain information to guide the foreground harmonization, which is regulated by well-tailored triplet losses. Extensive experiments on the benchmark dataset demonstrate the effectiveness of our proposed method. Code is available at https://github.com/bcmi/BargainNet.
