Yansong Tang

I am a tenure-track Assistant Professor of Shenzhen International Graduate School, Tsinghua University, where I direct the IVG@SZ (Intelligent Vision Group at Shenzhen, the sister group of the IVG at Beijing). Before that, I was a postdoctoral researcher at the Department of Engineering Science of the University of Oxford, working with Prof. Philip H. S. Torr. My current research interests lie in computer vision and pattern recognition.

I received my B.S. degree and Ph.D degree with honour from Tsinghua University, advised by Prof. Jie Zhou and Prof. Jiwen Lu. I have also spent time at Prof. Song-Chun Zhu's lab at University of California, Los Angeles (UCLA), and Microsoft Research Asia (MSRA), hosted by Dr. Han Hu and Dr. Xin Tong respectively.

I am looking for self-motivated Master/PhD/Postdoc. If you have top grades or coding skill, and are highly creative and interested in joining my group, please do not hesitate to send me your CV and transcripts of grades by Email after reading this file.

We propose a method to efficiently equip the Segment Anything Model (SAM) with the ability to generate regional captions by introducing a lightweight query-based feature mixer.

We propose a unified framework to achieve universal segmentation at a wide spectrum of granularities and levels.

We propose an open-vocabulary segmentation (OVS) method by calibrating in-vocabulary and domain-biased embedding space with generalized contextual prior of CLIP.

We propose an accurate data-free post-training quantization framework of diffusion models (ADP-DM) for efficient image generation.

We investigate a new problem called narrative action evaluation (NAE) and propose a prompt-guided multimodal interaction framework.

We propose a new method to exploit diffusion priors for human mesh recovery (HMR) in occlusion and crowded scenarios.

We proposed a unified framework for various efficient image enhancement tasks with generative diffusion priors.

We propose a hardware-algorithm co-optimizations method called MCUFormer to deploy vision transformers on microcontrollers with extremely limited memory, where we jointly design transformer architecture and construct the inference operator library to fit the memory resource constraint.

We present Tem-Adapter, a method that improves VQA by leveraging image-based knowledge and introducing temporal and semantic aligners.

We propose Skip-Plan, a condensed action space learning method for procedure planning in instructional videos.

We present FLAG3D, a large-scale 3D fitness activity dataset with language instruction.

LOGO is a new multi-person long-form video dataset for action quality assessment.

HorNet is a family of generic vision backbones that perform explicit high-order spatial interactions based on Recursive Gated Convolution.

We present a language-powered paradigm for ordinal regression.

We present an end-to-end hierarchical Transformer-based network for referring segmentation.

We present Bi-level Neural Volume Fusion, which leverages recent advances in neural implicit representations and neural rendering for dense 3D reconstruction. In order to incrementally integrate new depth maps into a global neural implicit representation, we propose a novel bi-level fusion strategy that considers both efficiency and reconstruction quality by design.

DenseCLIP is a new framework for dense prediction by implicitly and explicitly leveraging the pre-trained knowledge from CLIP.

COIN is currently the largest and most comprehensive instructional video analysis datasets with rich annotations.

We propose an uncertainty-aware score distribution learning method and extend it to a multi-path model for action quality assessment.
