At present, low-rank and sparse decomposition model has been widely used in the field of computer vision because of its excellent performance. However, the model still faces many challenges, such as being easily disturbed by dynamic background, failing to use prior information and heavy ...
We have managed to successfully exploit this idea for recovering a matrix as a summation of a Low-rank and a Sparse component from compressive measurements. When applied to the problem of construction of 4D Cardiac MR image sequences in real-time from highly under-sampled $k-$space data, ...
Recently, the low-rank and sparse decomposition model (LSDM) has been used for anomaly detection in hyperspectral imagery. The traditional LSDM assumes that the sparse component where anomalies and noise reside can be modeled by a single distribution which often potentially confuses weak anomalies and...
This paper explores the low-rank and sparse (LRS) decomposition to solve the problem of pansharpening. By exploiting the significant correlation among the multispectral (MS) image bands, the LRS decomposition is employed as a decorrelation tool, from which the spectral and spatial informations in MS...

本文提出一种衡量patch与transmission layer之间相似性的matric,基于图像强度和梯度。 不需要依据梯度进行reconstruction,所以color shift问题可以被极大改善,更多的图像细节得以被保留 introduction 把reflection removal的问题看成a sparse and low-rank matrix decomposition problem ...

Based on our observations, each comparison matrix can be naturally decomposed into a shared low-rank matrix, combined with a deviation error matrix which is the sum of a column-sparse matrix and a row-sparse one. The latent rank list can be easily extracted from the learned lowrank matrix....

This paper tackles this challenge by introducing an innovative framework for federated learning that harmoniously integrates principles from both Low-Rank and Sparse decomposition, denoted as FedLRS. We treat low-rank layers as discrete neural network layers and utilize decomposed weights to represent ...
