Adaptive direction-guided structure tensor total variation

作者：

Highlights：

• A two-stage variational image denoising framework is developed.

• An adaptive direction-guided structure tensor total variation prior is designed.

• A preprocessor that estimates directional parameters for the model is proposed.

• The utility is discussed in comparison with five alternative models.
