Wei Xiong

I am a research scientist at Adobe. Before that, I obtained my Ph.D. in Computer Science at the University of Rochester, under the supervision of Prof. Jiebo Luo. I am fortunate to have collaborated with Dr. Zhe Lin, Dr. Han Zhang, Dr. Ding Liu, Dr. Wenhan Luo, Dr. Lin Ma, and many excellent researchers during my internships.

My research interests include large generative models, diffusion models, personalized image generation and editing, image shadow synthesis, object novel view synthesis, multi-modal visual synthesis, and representation learning.

I am open to long-term university research collaborations, where I can provide mentorship for research projects, including: high-level and detailed research ideas, co-debugging if necessary, and connections to top researchers in the related fields. If you are interested, feel free to reach out with your resume.

I welcome any research discussions related to MLLM and visual generation. I believe that only the collision of ideas can produce good research. Feel free to reach out with your ideas via email. :)

IMPRINT: Generative Object Compositing by Learning Identity-Preserving Representation
Yizhi Song, Zhifei Zhang, Zhe Lin, Scott Cohen, Brian L. Price, Jianming Zhang, Soo Ye Kim, He Zhang, Wei Xiong, Daniel Aliaga
CVPR 2024
[PDF] [Project Page]

Our work achieves advanced image composition with a decent identity preservation, automatic object viewpoint/pose adjustment, color and lighting harmonization, and shadow synthesis. All these effects are achieved in a single framework!

Relightful Harmonization: Lighting-aware Portrait Background Replacement
Mengwei Ren*, Wei Xiong, Jae Shin Yoon, Zhixin Shu, Jianming Zhang, HyunJoon Jung, Guido Gerig, He Zhang
(* Work done while Mengwei was an intern at Adobe)
CVPR 2024
[PDF] [Project Page]

We introduce Relightful Harmonization, a lighting-aware diffusion model designed to seamlessly harmonize sophisticated lighting effect for the foreground portrait using any background image.

PHOTOSWAP: Personalized Subject Swapping in Images
Jing Gu, Yilin Wang, Nanxuan Zhao, Tsu-Jui Fu, Wei Xiong, Qing Liu, Zhifei Zhang, He Zhang, Jianming Zhang, HyunJoon Juang, Eric Wang
NeurIPS 2023
[PDF] [Project Page] [Code]

We present Photoswap, a novel approach that enables image editing experience through personalized subject swapping in existing images.

InstantBooth: Personalized Text-to-Image Generation without Test-Time Finetuning
Jing Shi*, Wei Xiong*, Zhe Lin, HyunJoon Jung (* Equal Contribution)
CVPR 2024
[PDF] [Project Page]

We propose InstantBooth, a novel approach built upon pre-trained text-to-image models that enables fast personalized text-to-image generation without test-time finetuning.

Guidance-driven Visual Synthesis with Generative Models
Wei Xiong
PhD Thesis 2022
[PDF]

My PhD thesis summarizes my main research works on Guided Visual Content Creation during my PhD program. Part I introduces guidance-driven visually pleasing data synthesis. Part II presents guidance-driven synthesis for downstream visual recognition tasks.

Moving Image 4

Unsupervised Low-light Image Enhancement with Decoupled Networks
Wei Xiong, Ding Liu, Xiaohui Shen, Chen Fang, Jiebo Luo
ICPR 2022
[PDF]

We are among the few pioneering works on unsupervised real-world low-light image enhancement. Specifically, we tackle the problem of enhancing real-world low-light images with significant noise in an unsupervised fashion. To this end, we explicitly decouple this task into two sub-problems: illumination enhancement and noise suppression.

Breast Cancer Induced Bone Osteolysis Prediction Using Temporal Variational Auto-Encoders
Wei Xiong*, Neil Yeung*, Shubo Wang, Haofu Liao, Jiebo Luo, Liyun Wang (* Equal Contribution)
BME Frontiers 2022
[PDF]

We adopt a temporal variational auto-encoder (T-VAE) model for bone osteolysis prediction on computed tomography (CT) images of murine breast cancer bone metastases.

Image Sentiment Transfer
Tianlang Chen, Wei Xiong, Haitian Zheng, Jiebo Luo
ACM MM 2020
[PDF]

We introduce an important but still unexplored research task Image Sentiment Transfer and propose an effective and flexible framework that performs image sentiment transfer at both the image level and the object level.

Example-Guided Image Synthesis across Arbitrary Scenes using Masked Spatial-Channel Attention and Self-Supervision
Haitian Zheng, Haofu Liao, Lele Chen, Wei Xiong, Tianlang Chen, Jiebo Luo
ECCV 2020
[PDF]

We tackle a challenging exemplar-guided image synthesis task, where the exemplar providing the style guidance is an arbitrary scene image which is semantically different from the given pixel-wise label map.

Fine-grained Image-to-Image Transformation towards Visual Recognition
Wei Xiong, Yutong He, Yixuan Zhang, Wenhan Luo, Lin Ma, Jiebo Luo
CVPR 2020
[PDF] [Supplementary]

We aim at transforming an image with a fine-grained category to synthesize new images that preserve the identity of the input image, which can thereby benefit the subsequent fine-grained image recognition and few-shot learning tasks.

CariGAN: Caricature Generation through Weakly Paired Adversarial Learning. Neural Networks
Wei Xiong*, Wenbin Li*, Haofu Liao, Jing Huo, Yang Gao, Jiebo Luo (* Equal Contribution)
Neural Networks 2020
[PDF]

We frame the caricature generation task as a weakly paired image-to-image translation task, and propose CariGAN model to generate high-fidelity caricature images from human faces with proper exaggerations.

Foreground-aware Image Inpainting
Wei Xiong, Jiahui Yu, Zhe Lin, Jimei Yang, Xin Lu, Connelly Barnes, Jiebo Luo
CVPR 2019
[PDF] [Hole Mask Dataset]

We propose a foreground-aware image inpainting system that explicitly disentangles structure inference and content completion. Our model first learns to predict the foreground contour, and then inpaints the missing region using the predicted contour as guidance.

Learning to generate time-lapse videos using multi-stage dynamic generative adversarial networks
Wei Xiong, Wenhan Luo, Lin Ma, Wei Liu, Jiebo Luo
CVPR 2018
[Project Page] [PDF] [Code] [Timelapse Video Dataset]

We propose a two-stage GAN model to generate vivid yet content-preserving time-lapse videos from only a single starting frame. To this end, we desentangle the task into content generation and motion enhancement.

Stacked Convolutional Denoising Auto-Encoders for Feature Representation
Bo Du*, Wei Xiong, Jia Wu, Lefei Zhang, Liangpei Zhang, Dacheng Tao
(* First author was my advisor)
IEEE Trans. Cybernetics 2017
[PDF]

We proposes an unsupervised feature learning model, named the Stacked Convolutional Denoising Auto-Encoders, that can map an image to hierarchical representations without any label information.

Regularizing Deep Convolutional Neural Networks with a Structured Decorrelation Constraint
Wei Xiong, Bo Du, Lefei Zhang, Ruimin Hu, Dacheng Tao
ICDM 2016
[PDF]

We propose a group regularization method, Structured Decorrelation Constraint (SDC), that regularizes the activations of the hidden layers in groups to achieve better generalization.
