DerainNeRF: 3D Scene Estimation with Adhesive Waterdrop Removal

no code implementations29 Mar 2024 Yunhao Li, Jing Wu, Lingzhe Zhao, Peidong Liu

When capturing images through the glass during rainy or snowy weather conditions, the resulting images often contain waterdrops adhered on the glass surface, and these waterdrops significantly degrade the image quality and performance of many computer vision algorithms.

SCINeRF: Neural Radiance Fields from a Snapshot Compressive Image

1 code implementation29 Mar 2024 Yunhao Li, Xiaodong Wang, Ping Wang, Xin Yuan, Peidong Liu

SCI is a cost-effective method that enables the recording of high-dimensional data, such as hyperspectral or temporal information, into a single image using low-cost 2D imaging sensors.

SingingHead: A Large-scale 4D Dataset for Singing Head Animation

no code implementations7 Dec 2023 Sijing Wu, Yunhao Li, Weitian Zhang, Jun Jia, Yucheng Zhu, Yichao Yan, Guangtao Zhai

Extensive comparative experiments with both SOTA 3D facial animation and 2D portrait animation methods demonstrate the necessity of singing-specific datasets in singing head animation tasks and the promising performance of our unified facial animation framework.

Layout and Task Aware Instruction Prompt for Zero-shot Document Image Question Answering

2 code implementations1 Jun 2023 Wenjin Wang, Yunhao Li, Yixin Ou, Yin Zhang

Instead, in this paper, we find that instruction-tuning language models like Claude and ChatGPT can understand layout by spaces and line breaks.
