Abstract
Summary
We present a fast and robust sparse time-invariant Radon transform (RT) in the mixed frequency-time domain. In the proposed method, the 2D alternating split Bregman algorithm is introduced to solve the optimization problem. Two proximity operators are applied to promote the robustness and sparseness of the RT in the time domain, while the forward and inverse RTs are computed in the frequency domain. With high efficiency and easy implementation, the proposed method is resistant to the outliers. The synthetic and real data examples demonstrate the better performance of the proposed method when applied on the noise-contaminated data, compared with the traditional non-robust RTs.
