Compressed Sensing Photoacoustic Imaging Reconstruction Using Elastic Net Approach.

Publication Type: Academic Journal

Source(s): Molecular Imaging. 12/20/2022, p1-9. 9p.

Abstract: Photoacoustic imaging involves reconstructing an estimation of the absorbed energy density distribution from measured ultrasound data. The reconstruction task based on incomplete and noisy experimental data is usually an ill-posed problem that requires...

An Adaptive Sparsity Estimation KSVD Dictionary Construction Method for Compressed Sensing of Transient Signal.

Publication Type: Academic Journal

Source(s): Mathematical Problems in Engineering. 7/20/2022, p1-12. 12p.

Abstract: Overcomplete dictionaries occupy an essential position in the sparse representation of signals. The dictionary construction method typically represented by K singular value decomposition (KSVD) is widely used because of its concise and efficient featur...

Heuristics for Finding Sparse Solutions of Linear Inequalities.

Publication Type: Academic Journal

Source(s): Asia-Pacific Journal of Operational Research. Feb2023, Vol. 40 Issue 1, p1-20. 20p.

Abstract: In this paper, we consider the problem of finding a sparse solution, with a minimal number of nonzero components, for a set of linear inequalities. This optimization problem is combinatorial and arises in various fields such as machine learning and com...

Diagonally scaled memoryless quasi–Newton methods with application to compressed sensing.

Publication Type: Academic Journal

Source(s): Journal of Industrial & Management Optimization. Jan2023, Vol. 19 Issue 1, p437-455. 19p.

Abstract: Memoryless quasi–Newton updating formulas of BFGS (Broyden–Fletcher–Goldfarb–Shanno) and DFP (Davidon–Fletcher–Powell) are scaled using well-structured diagonal matrices. In the scaling approach, diagonal elements as well as eigenvalues of the scaled m...

Distributed Compressed Hyperspectral Sensing Imaging Incorporated Spectral Unmixing and Learning.

Publication Type: Academic Journal

Source(s): Journal of Spectroscopy. 5/31/2022, p1-19. 19p.

Abstract: Compressed hyperspectral imaging is a powerful technique for satellite-borne and airborne sensors that can effectively shift the complex computational burden from the resource-constrained encoding side to a presumably more capable base-station decoder....
