An iterative support shrinking algorithm for $ℓ_{p}$ - $ℓ_{q}$ minimization

Zhifang Liu, Yanan Zhao, Chunlin Wu

We present an iterative support shrinking algorithm for $ℓ_{p}$ - $ℓ_{q}$ minimization~( $0 < p < 1 \leq q < \infty$ ). This algorithm guarantees the nonexpensiveness of the sign…

A General Truncated Regularization Framework for Contrast-Preserving Variational Signal and Image Restoration: Motivation and Implementation

Chunlin Wu, Zhifang Liu, Shuang Wen

Variational methods have become an important kind of methods in signal and image restoration - a typical inverse problem. One important minimization model consists of the squared $…
