“…5 and 6, we use the Matlab implementations provided by the authors of the corresponding papers with the following settings (we use Matlab notations for the filters and their arguments): Surprisingly, reverse filtering of linear filters (in this paper, we consider Gaussian and LoG filters) turns out to be a difficult task. In the case of periodic boundary conditions, perfect defiltering is delivered by the method of Dong et al (7) proposed in [4]. However, ( 7) is very sensitive to small perturbations and fails to recover images resulting from linear filters with non-periodic boundary conditions (see, e.g., Fig.…”

“…where quadratic energy E is defined by (8), r is a random image whose components are random numbers uniformly distributed on the interval [0, 1] and c n = 1/ √ n. One can see that (10) combines ( 9) with stochastic gradient descent ideas. (4). e Image-guided filtering using a smoothed guidance and defiltering with (4).…”
