Fast Terahertz Imaging Model Based on Group Sparsity and Nonlocal Self-Similarity

Fast Terahertz Imaging Model Based on Group Sparsity and Nonlocal Self-Similarity

In order to solve the problems of long-term image acquisition time and massive data processing in a terahertz time domain spectroscopy imaging system, a novel fast terahertz imaging model, combined with group sparsity and nonlocal self-similarity (GSNS), is proposed in this paper. In GSNS, the struc...
