NIMBLE: A Non-rigid Hand Model with Bones and Muscles

no code implementations9 Feb 2022 Yuwei Li, Longwen Zhang, Zesong Qiu, Yingwenqi Jiang, Nianyi Li, Yuexin Ma, Yuyao Zhang, Lan Xu, Jingyi Yu

Emerging Metaverse applications demand reliable, accurate, and photorealistic reproductions of human hands to perform sophisticated operations as if in the physical world.

An Arbitrary Scale Super-Resolution Approach for 3D MR Images via Implicit Neural Representation

1 code implementation27 Oct 2021 Qing Wu, Yuwei Li, Yawen Sun, Yan Zhou, Hongjiang Wei, Jingyi Yu, Yuyao Zhang

In the ArSSR model, the reconstruction of HR images with different up-scaling rates is defined as learning a continuous implicit voxel function from the observed LR images.

IREM: High-Resolution Magnetic Resonance (MR) Image Reconstruction via Implicit Neural Representation

no code implementations29 Jun 2021 Qing Wu, Yuwei Li, Lan Xu, Ruiming Feng, Hongjiang Wei, Qing Yang, Boliang Yu, Xiaozhao Liu, Jingyi Yu, Yuyao Zhang

For collecting high-quality high-resolution (HR) MR image, we propose a novel image reconstruction network named IREM, which is trained on multiple low-resolution (LR) MR images and achieve an arbitrary up-sampling rate for HR image reconstruction.

AutoSweep: Recovering 3D Editable Objectsfrom a Single Photograph

1 code implementation27 May 2020 Xin Chen, Yuwei Li, Xi Luo, Tianjia Shao, Jingyi Yu, Kun Zhou, Youyi Zheng

We base our work on the assumption that most human-made objects are constituted by parts and these parts can be well represented by generalized primitives.

PARN: Position-Aware Relation Networks for Few-Shot Learning

1 code implementation ICCV 2019 Ziyang Wu, Yuwei Li, Lihua Guo, Kui Jia

However, due to the inherent local connectivity of CNN, the CNN-based relation network (RN) can be sensitive to the spatial position relationship of semantic objects in two compared images.
