SAR Image Despeckling Based on Convolutional Denoising Autoencoder
Qianqian Zhang, Ruizhi Sun
In Synthetic Aperture Radar (SAR) imaging, despeckling is very important for image analysis,whereas speckle is known as a kind of multiplicative noise caused by the coherent imagin…
Tied pseudo links \& Pseudo knotoids
Ioannis Diamantis
In this paper we study the theory of {\it pseudo knots}, which are knots with some missing crossing information, and we introduce and study the theory of {\it pseudo tied links} an…
The 4-Adic Complexity of A Class of Quaternary Cyclotomic Sequences with Period 2p
Shiyuan Qiang, Yan Li, Minghui Yang +1
In cryptography, we hope a sequence over with period having larger -adic complexity. Compared with the binary case, the computation of 4-adic complexity of kn…
Integration and geometrization of Rota-Baxter Lie algebras
Li Guo, Honglei Lang, Yunhe Sheng
This paper first introduces the notion of a Rota-Baxter operator (of weight ) on a Lie group so that its differentiation gives a Rota-Baxter operator on the corresponding Lie al…
Shadow Removal by a Lightness-Guided Network with Training on Unpaired Data
Zhihao Liu, Hui Yin, Yang Mi +2
Shadow removal can significantly improve the image visual quality and has many applications in computer vision. Deep learning methods based on CNNs have become the most effective a…
Principal Component Analysis Based on T-norm Maximization
Xiang-Fei Yang, Yuan-Hai Shao, Chun-Na Li +2
Classical principal component analysis (PCA) may suffer from the sensitivity to outliers and noise. Therefore PCA based on -norm and -norm () have been s…
