Block Multipath Matching Pursuit
, 2023 In this paper, we propose a new reconstruction algorithm called Block Multipath Matching pursuit (BMMP), which is an extension of multipath matching pursuit (MMP) in block compressed sensing. Then the reconstruction condition of BMMP based on restricted isometric property (RIP) is established. In addition, we also provides a guarantee of reconstruction

A robust matching pursuit algorithm using information theoretic learning
, 2020 Current orthogonal matching pursuit (OMP) algorithms calculate the correlation between two vectors using the inner product operation and minimize the mean square error, which are both suboptimal when there are non-Gaussian noises or outliers in the ...

Optimization of Matching Pursuit Encoder Based on Analytical Approximation of Matching Pursuit Distortion [PDF]
2006 IEEE International Conference on Multimedia and Expo, 2006 Distortion of matching pursuit is calculated in terms of matching pursuit encoder parameters for uniformly distributed signals and dictionaries. Then, the MP encoder is optimized using the analytically derived approximation for MP distortion. Our simulation results show that this optimized MP encoder exhibits optimum performance for nonuniform signal ...

A New Generalized Orthogonal Matching Pursuit Method
Journal of Electrical and Computer Engineering, 2017 To improve the reconstruction performance of the generalized orthogonal matching pursuit, an improved method is proposed. Columns are selected from the sensing matrix by generalized orthogonal matching pursuit, and indices of the columns are added to the
