Super-resolution by polar Newton–Thiele׳s rational kernel in centralized sparsity paradigm

作者：

Highlights：

• The Newton–Thiele׳s rational interpolation function in the polar coordinates is proposed.

• The nonlinear interpolation in the polar coordinates is applied to image and video SR reconstruction.

• The novel SR model by polar Newton–Thiele׳s rational kernel in centralized sparsity paradigm is presented.
