Smooth SCAD: A Raised Cosine SCAD Type Thresholding Rule for Wavelet Denoising

Radhika Kulkarni, Aluisio Pinheiro, Brani Vidakovic +1

We introduce a smooth variant of the SCAD thresholding rule for wavelet denoising by replacing its piecewise linear transition with a raised cosine. The resulting shrinkage functio…
