VDIP-TGV: Blind Image Deconvolution via Variational Deep Image Prior Empowered by Total Generalized Variation

no code implementations30 Oct 2023 Tingting Wu, Zhiyan Du, Zhi Li, Feng-Lei Fan, Tieyong Zeng

However, we empirically find that VDIP struggles with processing image details and tends to generate suboptimal results when the blur kernel is large.

Retinex Image Enhancement Based on Sequential Decomposition With a Plug-and-Play Framework

no code implementations11 Oct 2022 Tingting Wu, Wenna Wu, Ying Yang, Feng-Lei Fan, Tieyong Zeng

In this paper, using a sequential Retinex decomposition strategy, we design a plug-and-play framework based on the Retinex theory for simultaneously image enhancement and noise removal.

DiscrimLoss: A Universal Loss for Hard Samples and Incorrect Samples Discrimination

no code implementations21 Aug 2022 Tingting Wu, Xiao Ding, Hao Zhang, Jinglong Gao, Li Du, Bing Qin, Ting Liu

To relieve this issue, curriculum learning is proposed to improve model performance and generalization by ordering training samples in a meaningful (e. g., easy to hard) sequence.

FedCos: A Scene-adaptive Federated Optimization Enhancement for Performance Improvement

1 code implementation7 Apr 2022 Hao Zhang, Tingting Wu, Siyao Cheng, Jie Liu

On the other hand, it enlarges the distances between local models, resulting in an aggregated global model with poor performance.

Color image segmentation based on a convex K-means approach

no code implementations17 Mar 2021 Tingting Wu, Xiaoyu Gu, Jinbo Shao, Ruoxuan Zhou, Zhi Li

The proposed variational method uses a combination of $l_1$ and $l_2$ regularizers to maintain edge information of objects in images while overcoming the staircase effect.
