Learning $\ell_1$-based analysis and synthesis sparsity priors using bi-level optimization

16 Jan 2014Yunjin ChenThomas PockHorst Bischof

We consider the analysis operator and synthesis dictionary learning problems based on the the $\ell_1$ regularized sparse representation model. We reveal the internal relations between the $\ell_1$-based analysis model and synthesis model... (read more)
