Revolutionizing AI Art Detection with Pixel-Level Precision
Recent advances in generative models have created highly realistic AI-generated images, posing challenges for authentication, especially in artistic contexts. This paper introduces a multi-task learning framework that combines image-level classification with pixel-level segmentation to enhance AI-generated artwork detection. The approach improves classification accuracy for backbone models (ResNet50 by 1.97%, ViT by 1.29%) and significantly boosts generalization to out-of-distribution (OOD) data (4.56% for ResNet50, 3.73% for ViT). This method effectively localizes manipulated regions and provides a more robust detection capability for complex AI-generated content, including partially manipulated images.

Multitask Learning for Detection
Our proposed framework integrates image-level classification with pixel-level segmentation. This dual approach allows for both a global assessment of image authenticity and precise localization of manipulated regions. Experimental results show that this joint optimization significantly enhances detection performance, especially for partially manipulated (inpainted) artworks.
Enhanced Generalization to OOD
A critical limitation of previous AI art detection methods is their poor generalization to out-of-distribution (OOD) data. By incorporating pixel-level segmentation supervision, our model demonstrates substantial improvements in generalizing to unseen generative models. This capability is vital for real-world scenarios where the specific generative model used for manipulation is often unknown.
Pixel-Level Segmentation Benefits
Unlike single-task classification, pixel-level segmentation enables the model to capture intricate textures, fine details, and localized manipulations. This fine-grained analysis is crucial for detecting complex AI-generated artworks, particularly those involving inpainting, where alterations are seamlessly integrated. Qualitative results show that the ViT-based model, in particular, captures precise segmentation boundaries.
Backbone Model Performance
The study evaluates both ResNet50 and Vision Transformer (ViT) as backbone networks. While both benefit from the multitask learning framework, ViT consistently outperforms ResNet50 in terms of accuracy and segmentation metrics, especially on more challenging inpainting tasks. Transformer-based architectures, with their attention mechanisms, prove highly effective for detecting subtle, inpainted regions.

The Challenge of Inpainting Detection
The study highlights the increased difficulty of detecting inpainted images compared with fully synthesized fake images. Inpainting datasets present a greater challenge for detection, as the manipulations are localized and often integrated smoothly into the surrounding content. Modern generative models like Stable Diffusion inherently support inpainting functionalities, making this form of deepfake art increasingly common. The proposed multitask framework addresses this by jointly optimizing classification and segmentation, enabling precise localization of manipulated regions.
