Regularized/model-based inversion techniques have emerged as a vital tool in improving tomographic reconstruction quality for microscopic applications. In this talk, we will present an algorithm for integrating data-driven regularizers based on convolutional sparse representations into the tomographic reconstruction framework. We will present results of using these techniques on scientific tomography data sets and compare them to the traditional regularizers used in these applications.
This presentation is part of Minisymposium “MS11 - Computational Imaging for Micro- and Nano-structures in Materials Science (2 parts)”
