Mind the RefGAP: Correcting Reference Attention in Diffusion-Based Visual Editing

Reference-guided diffusion editors struggle to faithfully reproduce user-provided references. We identify a potential bottleneck in diffusion editors: many methods provide limited reference-attention allocation. For example, in LoomVideo, edit-region queries assign less than 1% of their attention mass to the reference....

Talk, Render, Act: Integrating Social Gesture and Digital Face with Synchronized Speech for Conversational Humanoid Robot

Expressive humanoid interaction requires speech, facial animation, and body gestures to form a coherent response. However, many full-body humanoid robots produce speech and gestures without a visually expressive face, while talking-face animation and robot gesture generation are typically developed separately. We prese...

FADRA: Frequency-Aware Diffusion with Residual Adaptation for Video Face Restoration

FADRA, a frequency-aware diffusion framework with iterative residual adaptation specifically tailored for robust VFR, is proposed and a Frequency-Aware Loss is introduced that provides explicit supervision across multiple spectral bands, emphasizing visually sensitive frequency components that are crucial for perceptua...
