Critical Parameter Values and Reconstruction Properties of Discrete Tomography: Application to Experimental Fluid Dynamics
Stefania Petra, Christoph Schnörr, Andreas Schröder
We analyze representative ill-posed scenarios of tomographic PIV with a focus on conditions for unique volume reconstruction. Based on sparse random seedings of a region of interes…

Average Case Recovery Analysis of Tomographic Compressive Sensing
Stefania Petra, Christoph Schnörr
The reconstruction of three-dimensional sparse volume functions from few tomographic projections constitutes a challenging problem in image reconstruction and turns out to be a par…
