CWF: Consolidating Weak Features in High-quality Mesh Simplification

no code implementations24 Apr 2024 Rui Xu, Longdu Liu, Ningna Wang, Shuangmin Chen, Shiqing Xin, Xiaohu Guo, Zichun Zhong, Taku Komura, Wenping Wang, Changhe Tu

In mesh simplification, common requirements like accuracy, triangle quality, and feature alignment are often considered as a trade-off.

VC-Net: Deep Volume-Composition Networks for Segmentation and Visualization of Highly Sparse and Noisy Image Data

no code implementations14 Sep 2020 Yifan Wang, Guoli Yan, Haikuan Zhu, Sagar Buch, Ying Wang, Ewart Mark Haacke, Jing Hua, Zichun Zhong

A multi-stream convolutional neural network is proposed to learn the 3D volume and 2D MIP features respectively and then explore their inter-dependencies in a joint volume-composition embedding space by unprojecting the MIP features into 3D volume embedding space.

Attention-based Deep Reinforcement Learning for Multi-view Environments

no code implementations10 May 2019 Elaheh Barati, Xue-wen Chen, Zichun Zhong

In reinforcement learning algorithms, it is a common practice to account for only a single view of the environment to make the desired decisions; however, utilizing multiple views of the environment can help to promote the learning of complicated policies.
