ME-Net: Multi-Encoder Net Framework for Brain Tumor Segmentation

no code implementations21 Mar 2022 Wenbo Zhang, Guang Yang, He Huang, Weiji Yang, Xiaomei Xu, Yongkai Liu, Xiaobo Lai

Moreover, the serious voxel imbalance between the brain tumor and the background as well as the different sizes and locations of the brain tumor makes the segmentation of 3D images a challenging problem.

Depth Quality-Inspired Feature Manipulation for Efficient RGB-D Salient Object Detection

1 code implementation5 Jul 2021 Wenbo Zhang, Ge-Peng Ji, Zhuo Wang, Keren Fu, Qijun Zhao

To tackle this dilemma and also inspired by the fact that depth quality is a key factor influencing the accuracy, we propose a novel depth quality-inspired feature manipulation (DQFM) process, which is efficient itself and can serve as a gating mechanism for filtering depth features to greatly boost the accuracy.

Identifying modulation formats using integrated clustering algorithm

no code implementations28 Apr 2021 Wenbo Zhang, Jinmei Ye, Zixian Yue, Yuxiang Wang, Xulun Zhang, Xiaoguang Zhang, Lixia Xi

Modulation format identification (MFI) is crucial in next-generation optical networks such as cognitive optical networks.

Deformable Linear Object Prediction Using Locally Linear Latent Dynamics

1 code implementation26 Mar 2021 Wenbo Zhang, Karl Schmeckpeper, Pratik Chaudhari, Kostas Daniilidis

We empirically demonstrate that our approach can predict the rope state accurately up to ten steps into the future and that our algorithm can find the optimal action given an initial state and a goal state.

A Effective Carrier Phase Recovery Method in Tigth Time-Packing Fast than Nyquist Optical Communication System

no code implementations24 Aug 2020 Peng Sun, Xiaoguang Zhang, Dongwei Pan, Lixia Xi, Wenbo Zhang, Xianfeng Tang

We propose a new scheme that combines polybinary transformaton and corrected-BPS to compensate noise for PDM-FTN-QPSK when its accelerated factor is 0. 5, which has 3. 3 dB OSNR gain when phase noise is 800 kHz.

IncNSA: Detecting communities incrementally from time-evolving networks based on node similarity

1 code implementation International Journal of Modern Physics C 2020 Xing Su, Jianjun Cheng, Haijuan Yang, Mingwei Leng, Wenbo Zhang, Xiaoyun Chen

When the network evolves from the previous snapshot to the current one, the proposed method only considers the community affiliations of partial nodes efficiently, which are either newborn nodes or some active nodes from the previous snapshot.
