Sparse Solution of Underdetermined Linear Equations by Stagewise Orthogonal Matching Pursuit
compressed sensing decoding error-correcting codes
2015/8/21
Finding the sparsest solution to underdetermined systems of linear equations y = Φx is NP-hard
in general. We show here that for systems with ‘typical’/‘random’ Φ, a good approximation to the
sparse...

Hyperspectral images contain rich and fine spectral information, an improvement of land use/cover classification accuracy is
expected from the use of such images. However, the classification methods...

In this paper, we present coherence-based performance guarantees of Orthogonal Matching Pursuit (OMP) for both support recovery and signal reconstruction of sparse signals when the measurements are co...
Orthogonal Matching Pursuit with Noisy and Missing Data: Low and High Dimensional Results
Orthogonal Matching Pursuit Noisy and Missing Data High Dimensional Results Statistics Theory

本文研究了心电信号在身份识别中的应用，提出了基于快速傅里叶变换的匹配追踪心电特征提取算法。在预处理阶段，对心电信号进行消噪、标准化和质量检测等预处理，有效去除了心电信号中的噪声和心率变异所带来的干扰。特征提取阶段，对心电模板进行基于快速傅里叶变换的匹配追踪稀疏分解，原子的时频参数和投影值作为特征参数，然后构建支持向量机分类器，实现了身份识别。最后利用MIT-BIH的ST Change、PTB、QT...
In this paper, we consider the problem of compressed sensing where the goal is to recover almost all the sparse vectors using a small number of fixed linear measurements. For this problem, we propose ...
