This repo contains the codes for the TNNLS paper. we propose a complex convolutional sparse coding (ComCSC) algorithm and its gradient regularized version (ComCSC-GR) for interferometric phase restoration. Our method outperforms the state-of-the-art methods. The codes are modified from SPORCO for adapting to complex images.
10, 000 Monte-Carlo simulations for evaluating the compared methods on the expected values and standard deviations of step function approximation. The amplitude is constant and the coherence value is set as 0.3.
train_cpx_dic.m uses ComCSC and ComCSC-GR to train the complex convolutional dictionaries based on the simulated interferograms train_cpxs.mat.
recon_peaks_cpx_comp.mlx gives a demo using the learned convolutional dictionaries to restore the clean interferogram.
