MDC-Net: Multi-dimensional Cross-Domain Collaborative Network for Image Manipulation Localization
摘要
With the widespread use of image editing tools, image manipulation has become increasingly easy, raising significant concerns about content authenticity across various fields. As a result, image manipulation localization (IML) techniques have become crucial. Most current methods perform pixel-level tampering detection by learning discriminative features. However, these methods typically rely on single-modality features and shallow fusion strategies, failing to capture the deep correlations between features from different domains. To address this issue, we propose the Multi-Dimensional Cross-Domain Collaborative Network (MDC-Net). MDC-Net combines RGB, noise, texture, and edge features, using wavelets with dynamically weighted correlations to extract texture features and designing fusion modules to exploit cross-domain complementarity with noise fully. Additionally, we extract edge features through differentiated edge detection operators and attention-guided feature interaction mechanisms to enhance boundary information representation. Experimental results demonstrate that MDC-Net achieves superior and stable performance compared to existing methods across several public image manipulation datasets.
