I am Shiyao Xu (徐诗瑶), currently a research scientist at Cybever Inc. My research interests lie in 3D-aware understanding, editing, and generation, and also neural rendering.
I also worked with Prof. Yebin Liu, Prof. Hongwen Zhang, Lingzhi Li, Dr. Li Shen, Prof. Zhouhui Lian.

I just obtain my M.Sc. degree from from Wangxuan Institute of Computer Techonology(WICT) at Peking University, China, 2023, supervised by Prof. Zhouhui Lian. I did my bachelors at Dalian University of Technology, China, 2020.

I am looking for a PhD position or full-time, -paid research assistant opportunity starting from now. Please freely contact me! :)

    CVPRW 2023, CVPR Workshop on Generative Models for Computer Vision
    [Project] [PDF] [Code](tbc) [Poster]

    We propose a more efficient method, DeSRF, to stylize the radiance field, which also transfers style information to the geometry according to the input style.

    [Project](tbc) [PDF] [DOI] [Code]

    We propose a novel 3D generative model to translate a real-world face image into its corresponding 3D avatar with only a single style example provided. Our model is 3D-aware in sense and also able to do attribute editing, such as smile, age, etc directly in the 3D domain.

    We propose an automatically method to transfer the dynamic texture of a given video to a still image.

    Abstract
      How to automatically transfer the dynamic texture of a given video to the target still image is a challenging and ongoing problem. In this paper, we propose to handle this task via a simple yet effective model that utilizes both PatchMatch and Transformers. The key idea is to decompose the task of dynamic texture transfer into two stages, where the start frame of the target video with the desired dynamic texture is synthesized in the first stage via a distance map guided texture transfer module based on the PatchMatch algorithm. Then, in the second stage, the synthesized image is decomposed into structure-agnostic patches, according to which their corresponding subsequent patches can be predicted by exploiting the powerful capability of Transformers equipped with VQ-VAE for processing long discrete sequences. After getting all those patches, we apply a Gaussian weighted average merging strat- egy to smoothly assemble them into each frame of the target stylized video. Experimental results demonstrate the effectiveness and superiority of the proposed method in dynamic texture transfer compared to the state of the art.
