Abstract:
With the widespread application of image editing software, image manipulation localization has become a focal point and promising research. Existing neural networks for image manipulation primarily rely on RGB and noise features to accurately identify tampered areas within images. However, in practical image manipulation localization tasks, noise features extracted from RGB images alone are often insufficient to effectively address tampering issues. Furthermore, existing encoder-decoder models for image manipulated localization often overlook the direct interactions between different layers during the decoding process, which hinders the effective transfer of deep semantic information to shallow features, thereby impacting the ability to accurately identify manipulated areas. To address the challenges previously identified, this paper presents a dynamically adaptive noise extraction module and achieves inter-layer information exchange in the decoder by fusing output features from different layers to extract edge information. We adaptively map RGB images to an appropriate color space using linear transformations and then extract noise features, leveraging the differences in color blocks to effectively uncover features of tampering. In addition, we integrate features across multiple decoder layers, employ deep multi-scale edge supervision to impose constraints, and introduce a dynamic ringed residual module to further enhance feature representation. Extensive experiments demonstrate that our approach achieves competitive results on diverse large-scale image datasets, exhibiting superior precision and robustness compared with most state-of-the-art methods.
