Abstract
Rank order filters are non-linear filters which choose an output based on its rank within a window of sample inputs determined by sorting the inputs. Rank order filters are a subset of the class of stack filters [1-5] which are also non-linear. A new systematic method for applying block processing, which transforms single-input single-output structures to parallel-input parallel-output structures, for non- recursive rank order and stack filters is presented in this paper. This method takes advantage of shared substructures within the block structure to efficiently generate a block filter whose complexity can be up to one-half the size of the original filter structure times the block size. This method can also be applied to two-dimensional non-recursive rank order filters.
