-free modules over the Lie algebras of differential operators
Munayim Dilxat, Shoulan Gao, Dong Liu +1
In this paper, we consider some non-weight modules over the Lie algebra of Weyl type. First, we determine the modules whose restriction to are free of rank over th…
Flow-Guided Transformer for Video Inpainting
Kaidong Zhang, Jingjing Fu, Dong Liu
We propose a flow-guided transformer, which innovatively leverage the motion discrepancy exposed by optical flows to instruct the attention retrieval in transformer for high fideli…
Towards Hybrid-Optimization Video Coding
Shuai Huo, Dong Liu, Li Li +3
Video coding is a mathematical optimization problem of rate and distortion essentially. To solve this complex optimization problem, two popular video coding frameworks have been de…
Local discontinuous Galerkin method for the Backward Feynman-Kac Equation
Dong Liu, Weihua Deng
Anomalous diffusions are ubiquitous in nature, whose functional distributions are governed by the backward Feynman-Kac equation. In this paper, the local discontinuous Galerkin (LD…
A nonlinear weighted anisotropic total variation regularization for electrical impedance tomography
Yizhuang Song, Yanying Wang, Dong Liu
This paper proposes a nonlinear weighted anisotropic total variation (NWATV) regularization technique for electrical impedance tomography (EIT). The key idea is to incorporate the…
Retinal Vessel Segmentation with Pixel-wise Adaptive Filters
Mingxing Li, Shenglong Zhou, Chang Chen +3
Accurate retinal vessel segmentation is challenging because of the complex texture of retinal vessels and low imaging contrast. Previous methods generally refine segmentation resul…
