ObjectFormer for Image Manipulation Detection and Localization |
J. Wang et al., “ObjectFormer for Image Manipulation Detection and Localization,” 2022 Ieee Cvf Conf Comput Vis Pattern Recognit Cvpr, vol. 00, pp. 2354–2363, 2022, doi: 10.1109/cvpr52688.2022.00240.
作者提出了使用frequency特征以及将它和RGB特征结合,以embedding的形式输入到encoder里面,主要的贡献点是1. 用了这个high frequency feature,2. 对frequency feature应用了一个边界敏感上下文不一致模块boundary-sensitive contextual incoherence module,用来对特征做fine-grain,3. 利用了object prototype,学习mid-level feature。
作者在做消融研究的时候,baseline是efficientNet-B4?因为他用的backbone就是efficient-B4,
