Analysis of the Block Coordinate Descent Method for Linear Ill-Posed Problems
Simon Rabanser, Lukas Neumann, Markus Haltmeier
Block coordinate descent (BCD) methods approach optimization problems by performing gradient steps along alternating subgroups of coordinates. This is in contrast to full gradient…
Stochastic Proximal Gradient Algorithms for Multi-Source Quantitative Photoacoustic Tomography
Simon Rabanser, Lukas Neumann, Markus Haltmeier
The development of accurate and efficient image reconstruction algorithms is a central aspect of quantitative photoacoustic tomography (QPAT). In this paper, we address this issues…
Analysis of the Linearized Problem of Quantitative Photoacoustic Tomography
Markus Haltmeier, Lukas Neumann, Linh V. Nguyen +1
Quantitative image reconstruction in photoacoustic tomography requires the solution of a coupled physics inverse problem involvier light transport and acoustic wave propagation. In…
Single-stage reconstruction algorithm for quantitative photoacoustic tomography
Markus Haltmeier, Lukas Neumann, Simon Rabanser
The development of efficient and accurate image reconstruction algorithms is one of the cornerstones of computed tomography. Existing algorithms for quantitative photoacoustic tomo…
