DOI: 10.1109/tci.2018.2858139
Abstract: We present a novel algorithm for computed tomography that simultaneously computes a reconstruction and a corresponding segmentation. Our algorithm uses learned dictionaries for both the reconstruction and the segmentation, constructed via discriminative dictionary learning using… read more here.
