A Class of Fourth‐Order Telegraph‐Diffusion Equations for Image Restoration
A class of nonlinear fourth‐order telegraph‐diffusion equations (TDE) for image restoration are proposed based on fourth‐order TDE and bilateral filtering. The proposed model enjoys the benefits of both fourth‐order TDE and bilateral filtering, which is not only edge preserving and robust to noise but also avoids the staircase effects. The …
