Multi-layer Clustering-based Residual Sparsifying Transform for Low-dose CT Image Reconstruction

no code implementations22 Mar 2022 Xikai Yang, Zhishen Huang, Yong Long, Saiprasad Ravishankar

In this study, we propose a network-structured sparsifying transform learning approach for X-ray computed tomography (CT), which we refer to as multi-layer clustering-based residual sparsifying transform (MCST) learning.
