The goal of this communication is to shed new light on a wavelet-based denoising method developed by Hadjileontiadis et al. [1], [2], which is derived from an iterative denoising algorithm by Coifman and Wickerhauser [3], [4]. The underlying algorithm is revisited and interpreted as a fixed point algorithm. This allows to derive a new version of the algorithm largely increasing computational efficiency.
