MorphUNet: Alpha-Controlled Biometric Transport for Diffusion-Based Face Morphing Attacks

MorphUNet is the first diffusion-based morphing framework using trainable parent-separated dual cross-attention inside the denoising U-Net: a Biometric Transport Layer carrying parent-specific identity evidence through denoising, attending to each parent separately before combining residuals via the morphing parameter alpha.
