Directional Total Generalized Variation Regularization

Understand

In inverse problems, prior information and a priori-based regularization techniques play important roles.

• In this paper, we focus on image restoration problems, especially on restoring images whose texture mainly follow one direction.
• In order to incorporate the directional information, we propose a new directional total generalized variation (DTGV) functional, which is based on total generalized variation (TGV) by Bredies \textit{et al}.
