GeoDiff4D: Geometry-Aware Diffusion for 4D Head Avatar Reconstruction
Chao Xu, Xiaochen Zhao, Xiang Deng +4
Reconstructing photorealistic and animatable 4D head avatars from a single portrait image remains a fundamental challenge in computer vision. While diffusion models have enabled re…
Plan-X: Instruct Video Generation via Semantic Planning
Lun Huang, You Xie, Hongyi Xu +7
Diffusion Transformers have demonstrated remarkable capabilities in visual synthesis, yet they often struggle with high-level semantic reasoning and long-horizon planning. This lim…
X-Streamer: Unified Human World Modeling with Audiovisual Interaction
You Xie, Tianpei Gu, Zenan Li +7
We introduce X-Streamer, an end-to-end multimodal human world modeling framework for building digital human agents capable of infinite interactions across text, speech, and video w…
X-UniMotion: Animating Human Images with Expressive, Unified and Identity-Agnostic Motion Latents
Guoxian Song, Hongyi Xu, Xiaochen Zhao +5
We present X-UniMotion, a unified and expressive implicit latent representation for whole-body human motion, encompassing facial expressions, body poses, and hand gestures. Unlike…
X-Actor: Emotional and Expressive Long-Range Portrait Acting from Audio
Chenxu Zhang, Zenan Li, Hongyi Xu +8
We present X-Actor, a novel audio-driven portrait animation framework that generates lifelike, emotionally expressive talking head videos from a single reference image and an input…
X-NeMo: Expressive Neural Motion Reenactment via Disentangled Latent Attention
Xiaochen Zhao, Hongyi Xu, Guoxian Song +6
We propose X-NeMo, a novel zero-shot diffusion-based portrait animation pipeline that animates a static portrait using facial movements from a driving video of a different individu…
