computationally fast but have the tendency to amplify noise and can even
introduce artifacts. Generally they are not successful when studying small,
intracellular structures and dynamic processes. More sophisticated, nonlinear
methods involve iterative constrained algorithms, which allow enforcement of
specific constraints. The nonlinear category also includes blind deconvolution
algorithms [25], which do not require knowledge of the psf, for it is estimated
from the data during the process. Time-lapse imaging of thick samples may
require even more sophisticated, space-variant deconvolution methods.
While some authors have advocated always to deconvolve image data if
possible [23], the question of whether deconvolution, as a separate preprocessing
