Follow-Your-Click: Open-domain Regional Image Animation via Motion Prompts

AAAI 2025technical

Despite recent advances in image-to-video generation, better controllability and local animation are less explored. Most existing image-to-video methods are not locally aware and tend to move the entire scene. However, human artists may need to control the movement of different objects or regions. A…

HunyuanPortrait: Implicit Condition Control for Enhanced Portrait Animation

CVPR 2025poster

We introduce HunyuanPortrait, a diffusion-based condition control method that employs implicit representations for highly controllable and lifelike portrait animation. Given a single portrait image as an appearance reference and video clips as driving templates, HunyuanPortrait can animate the chara…

Robustness-Guided Image Synthesis for Data-Free Quantization

AAAI 2024technical

Quantization has emerged as a promising direction for model compression. Recently, data-free quantization has been widely studied as a promising method to avoid privacy concerns, which synthesizes images as an alternative to real training data. Existing methods use classification loss to ensure the…

Seeing What You Miss: Vision-Language Pre-Training With Semantic Completion Learning

CVPR 2023poster

Cross-modal alignment is essential for vision-language pre-training (VLP) models to learn the correct corresponding information across different modalities. For this purpose, inspired by the success of masked language modeling (MLM) tasks in the NLP pre-training area, numerous masked modeling tasks…

Egocentric Video-Language Pretraining

NeurIPS 2022accept

Video-Language Pretraining (VLP), which aims to learn transferable representation to advance a wide range of video-text downstream tasks, has recently received increasing attention. Best performing works rely on large-scale, 3rd-person video-text datasets, such as HowTo100M. In this work, we exploit…
