Furthermore, for the iterative filter
initialization no training cycle in a batch form is required.
Geometric filter is a nonlinear, iterative filter
which takes into account the image morphology.
It is a nonlinear and non iterative filter
. It derives from a blur filter but it prevents blurring across edges by decreasing the weight of pixels when the intensity difference is too large.
Clearly, the proposed algorithm is a robust minimax iterative filter
because it is obtained by minimizing estimation error under worst possible steering command.
