Analysis of Adaptive Synchrosqueezing Transform with a Time-varying Parameter

no code implementations22 Aug 2020 Jian Lu, Qingtang Jiang, Lin Li

A model-guided deep network for limited-angle computed tomography

1 code implementation10 Aug 2020 Wei Wang, Xiang-Gen Xia, Chuanjiang He, Zemin Ren, Jian Lu, Tianfu Wang, Baiying Lei

In this paper, we first propose a variational model for the limited-angle computed tomography (CT) image reconstruction and then convert the model into an end-to-end deep network. We use the penalty method to solve the model and divide it into three iterative subproblems, where the first subproblem completes the sinograms by utilizing the prior information of sinograms in the frequency domain and the second refines the CT images by using the prior information of CT images in the spatial domain, and the last merges the outputs of the first two subproblems.
