Instilling an Active Mind in Avatars via Cognitive Simulation

ICLR 2026oral

Current video avatar models can generate fluid animations but struggle to capture a character's authentic essence, primarily synchronizing motion with low-level audio cues instead of understanding higher-level semantics like emotion or intent. To bridge this gap, we propose a novel framework for gen…

TAP: A Token-Adaptive Predictor Framework for Training-Free Diffusion Acceleration

CVPR 2026

Diffusion models achieve strong generative performance but remain slow at inference due to the need for repeated full-model denoising passes. We present Token-Adaptive Predictor (TAP), a training-free, probe-driven framework that adaptively selects a predictor for each token at every sampling step.

IDA-VLM: Towards Movie Understanding via ID-Aware Large Vision-Language Model

ICLR 2025poster

The rapid advancement of Large Vision-Language models (LVLMs) has demonstrated a spectrum of emergent capabilities. Nevertheless, current models only focus on the visual content of a single scenario, while their ability to associate instances across different scenes has not yet been explored, which…

OOTDiffusion: Outfitting Fusion Based Latent Diffusion for Controllable Virtual Try-On

AAAI 2025technical

We present OOTDiffusion, a novel network architecture for realistic and controllable image-based virtual try-on (VTON). We leverage the power of pretrained latent diffusion models, designing an outfitting UNet to learn the detailed garment features. Without a redundant warping process, the garment f…

Prompt-A-Video: Prompt Your Video Diffusion Model via Preference-Aligned LLM

ICCV 2025poster

Text-to-video models have made remarkable advancements through optimization on high-quality text-video pairs, where the textual prompts play a pivotal role in determining quality of output videos. However, achieving the desired output often entails multiple revisions and iterative inference to refin…

ViGoR: Improving Visual Grounding of Large Vision Language Models with Fine-Grained Reward Modeling

ECCV 2024poster

"By combining natural language understanding, generation capabilities, and breadth of knowledge of large language models with image perception, recent large vision language models (LVLMs) have shown unprecedented visual reasoning capabilities. However, the generated text often suffers from inaccurat…

Humble Teachers Teach Better Students for Semi-Supervised Object Detection

CVPR 2021poster

We propose a semi-supervised approach for contemporary object detectors following the teacher-student dual model framework. Our method is featured with 1) the exponential moving averaging strategy to update the teacher from the student online, 2) using plenty of region proposals and soft pseudo-labe…

Learning to Sit: Synthesizing Human-Chair Interactions via Hierarchical Control

AAAI 2021technical

Recent progress on physics-based character animation has shown impressive breakthroughs on human motion synthesis, through imitating motion capture data via deep reinforcement learning. However, results have mostly been demonstrated on imitating a single distinct motion pattern, and do not generaliz…

OASIS: A Large-Scale Dataset for Single Image 3D in the Wild

CVPR 2020poster

Single-view 3D is the task of recovering 3D properties such as depth and surface normals from a single image. We hypothesize that a major obstacle to single-image 3D is data. We address this issue by presenting Open Annotations of Single Image Surfaces (OASIS), a dataset for single-image 3D in the w…
