The challenge focuses on detecting synthetic content and localizing manipulated regions in images collected from real-world, in-the-wild sources. It consists of two complementary tasks:

• Task A: Real vs. Synthetic Image Classification
• Task B: Manipulated Region Localization

We welcome participation from researchers and practitioners in computer vision, multimedia forensics, machine learning, and related fields.
