Motion4Motion: Motion Transfer Across Subjects at Inference

Ling-Hao Chen, Zixin Yin, Duomin Wang, Xianfang Zeng, Gang Yu

ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques, ACM SIGGRAPH 2026,

Oral Presentation

The first training-free cross-species motion transfer framework that models motion flow instead of skeletons, enabling motion transfer across diverse subjects such as human-to-panda directly at inference time.

ReasonEdit: Towards Reasoning-Enhanced Image Editing Models

Step1X-Image Team (Core Member)

2026 IEEE Conference on Computer Vision and Pattern Recognition, CVPR 2026,

We show that unlocking MLLM reasoning via a thinking–editing–reflection loop significantly improves image editing accuracy by enhancing instruction understanding and automatic error correction, achieving consistent gains over state-of-the-art diffusion-based editors such as Step1X-Edit and Qwen-Image-Edit.

Training-Free Text-Guided Color Editing with Multi-Modal Diffusion Transformer

The Fourteenth International Conference on Learning Representations, ICLR 2026,

Completed from scratch in 30 days

We introduce ColorCtrl, a training-free method for text-guided color editing in images and videos. It enables precise control of color attributes while preserving geometry and material consistency. Experiments on SD3, FLUX.1-dev, and CogVideoX show that ColorCtrl outperforms existing training-free and commercial models, including GPT-4o and FLUX.1 Kontext Max, and generalizes well to instruction-based editing frameworks.

LazyDrag: Enabling Stable Drag-Based Editing on Multi-Modal Diffusion Transformers via Explicit Correspondence

Zixin Yin, Xili Dai, Duomin Wang, Xianfang Zeng, Lionel M. Ni, Gang Yu, Heung-Yeung Shum

The Fourteenth International Conference on Learning Representations, ICLR 2026,

Completed from scratch in 30 days

LazyDrag, a drag-based image editing method for Multi-Modal Diffusion Transformers, eliminates implicit point matching, enabling precise geometric control and text guidance without test-time optimization.

SpeakerVid-5M: A Large-Scale High-Quality Dataset for audio-visual Dyadic Interactive Human Generation

Youliang Zhang, Zhaoyang Li, Duomin Wang, Jiahe Zhang, Deyu Zhou, Zixin Yin, Xili Dai, Gang Yu, Xiu Li

The Fourteenth International Conference on Learning Representations, ICLR 2026,

We introduce SpeakerVid-5M, the first large-scale dataset designed specifically for the audio-visual dyadic interactive virtual human task.

ConsistEdit: Highly Consistent and Precise Training-free Visual Editing

Zixin Yin, Ling-Hao Chen, Lionel M. Ni, Xili Dai

ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia, ACM SIGGRAPH Asia 2025,

Oral Presentation (Completed from scratch in 21 days)

ConsistEdit is a training-free attention control method for MM-DiT that enables precise, structure-aware image and video editing. It supports multi-round edits with strong consistency and achieves state-of-the-art performance without manual design or test-time tuning.

Motion2Motion: Cross-topology Motion Retargeting with Sparse Correspondence

Ling-Hao Chen, Yuhong Zhang, Zixin Yin, Zhiyang Dou, Xin Chen, Jingbo Wang, Taku Komura, Lei Zhang,

ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia, ACM SIGGRAPH Asia 2025,

Oral Presentation

This work addresses animation retargeting across characters with differing skeletal topologies. Motion2Motion is a novel, training-free framework that requires only a few target motions and sparse bone correspondences. It overcomes topological inconsistencies without large datasets. Extensive evaluations show strong performance in both similar and cross-species settings, with applications in user-facing tools.

UniVerse-1: Unified Audio-Video Generation via Stitching of Experts

Duomin Wang, Wei Zuo, Aojie Li, Ling-Hao Chen, Xinyao Liao, Deyu Zhou, Zixin Yin, Xili Dai, Daxin Jiang, Gang Yu

arXiv, 2509.06155,

We introduce UniVerse-1, a unified, Veo-3-like model capable of simultaneously generating coordinated audio and video. To enhance training efficiency, we bypass training from scratch and instead employ a stitching of expertise technique.

Talking Head Generation with Probabilistic Audio-to-Visual Diffusion Priors

Zhentao Yu, Zixin Yin (co-first), Deyu Zhou, Duomin Wang, Finn Wong, Baoyuan Wang

2023 IEEE International Conference on Computer Vision, ICCV 2023,

We introduce a simple and novel framework for one-shot audio-driven talking head generation. Unlike prior works that require additional driving sources for controlled synthesis in a deterministic manner, we instead probabilistically sample all the holistic lip-irrelevant facial motions to semantically match the input audio while still maintaining both the photo-realism of audio-lip synchronization and the overall naturalness.

Progressive Disentangled Representation Learning for Fine-Grained Controllable Talking Head Synthesis

Duomin Wang, Yu Deng, Zixin Yin, Heung-Yeung Shum, Baoyuan Wang

2023 IEEE Conference on Computer Vision and Pattern Recognition, CVPR 2023,

We present a novel one-shot talking head synthesis method that achieves disentangled and fine-grained control over lip motion, eye gaze&blink, head pose, and expression. We represent different motions via disentangled latent representations and leverage an image generator to synthesize talking heads from them.
