Recently, there are increasing attention paid on compressed sensing which is distinct different from traditional signal processing and image reconstructed from indirect or incomplete measurement, especially ℓ1-norm problem which is transformed from compressive sensing. The idea of ℓ1-regularization, as the one of ℓ1-norm, has been receiving a lot of interest in signal processing, image recovery and statistic, etc. This paper will introduces a continuation log-barrier method for solving ℓ1-regularized least squares problem in the field of compressive sensing, which is a second-order method. Our work is inspired by the work in [4] and continuation idea, and the paper will introduce the continuation technique to increase the convergence rate. Therefore, Our continuation log-barrier method for ℓ1-regularized least square problem is accurate and fast in the sense. © 2011 Springer-Verlag Berlin Heidelberg.
