As to non-Bayesian approaches, Lee's sigma filter has
evolved into bilateral filtering, which has possibly inspired
nonlocal filtering, excellent examples of which are found
both in spatial and in wavelet domains. In parallel, total
variation has emerged as a powerful regularization technique that can be specialized to the signal dependent noise
model and allows constraints to be set on several mathematical properties of the output image. As an example,
setting a constraint on L1 norm definitely avoids glitches
and other impairments. Presently, computational issues
are mainly responsible for the moderate, yet increasing,
popularity of such methods among users.
New horizons are undoubtedly in the direction of compressed sensing, of which denoising seems to be one of the
most promising application, notwithstanding objective
difficulties come from the signal dependent, and hence
nonstationary, noise model. Given the huge effort of
researchers in this area, new developments and applications to despeckling are expected in a near future. Computational issues are also the main drawback of algorithms
based on compressed sensing, with respect to spatial and
wavelet domain Bayesian algorithms. The ever increasing
diffusion of multiprocessor systems will be beneficial for
methods that can be easily parallelized.
