Discrete and Continuous Sparse Recovery Methods and Their Applications
… analysis model, with an emphasis on efficient algorithms and performance analysis.</p><p>In considering the sparse recovery method with structured dictionary mismatches for the synthesis model, we exploit the joint sparsity between the mismatch parameters and original sparse signal. We …

Modeling and Development of Iterative Reconstruction Algorithms in Emerging X-ray Imaging Technologies
… discrete imaging models that form the basis for iterative image reconstruction. Secondly, to improve image quality in grating-based phase-contrast tomography, we incorporate 2nd order statistical properties of the object property sinograms, including correlations between them, into the …
