[TCSVT Major Revision] MoAnimate: Bridging the Motion-Oriented Latent Representation Gaps in Human Animation
Haipeng Fang, Fan Tang, Zhihao Sun, Ziyao Huang, Juan Cao, Sheng Tang, and Yongdong Zhang
IEEE Transactions on Circuits and Systems for Video Technology (TCSVT)
TL;DR: We address unguided initialization and inefficient interactions in consistency modeling with MoAnimate, a dual-stream motion framework that improves entity consistency across benchmarks and generalization scenarios.

[CVPR 2025] Attend to Not Attended: Structure-then-Detail Token Merging for Post-training DiT Acceleration
Haipeng Fang, Sheng Tang Juan Cao, Enshuo Zhang, Fan Tang, and Tong-Yee Lee
Proceedings of the 42nd IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR 2025)
Preprint / Paper /
TL;DR: We analyze the diffusion prior in DiT, identify the locations and degrees of redundancy in DiT, and design a “structure-then-detail” token merging method for post-training diffusion transformer acceleration.
[ICASSP 2025] FR2ViT: Finetuning-free Token Reduction for Dense Prediction Through a Refinement-Reactivation Architecture
Haipeng Fang, Ziheng Wu, Xinyi Zou, Jun Huang, Juan Cao, and Sheng Tang
Proceedings of the 50th IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2025)
Paper
TL;DR: We analyze the conflict between token reduction and dense prediction tasks, and design a Refinement-Reactivation Architecture for dense prediction.
2024
