Image Variational Denoising Using Gradient Fidelity on Curvelet Shrinkage
Image Variational Denoising Using Gradient Fidelity on Curvelet Shrinkage
A new variational image model is presented for image restoration using a combination of the curvelet shrinkage method and the total variation (TV) functional. In order to suppress the staircasing effect and curvelet-like artifacts, we use the multiscale curvelet shrinkage to compute an initial estimated image, and then we propose …
