Comments on "Theoretical Analysis of the Max/ Median Filter"
David Burshtein, Ehud Weinstein, David Burshtein, Ehud Weinstein · 1988
In the above paper,' an approach (the maxlmedian filter) to remove noise from images without distorting geometrical informa- tion was introduced. The proposed filter structure, due to its asym- metrical nature, is able to preserve only the subtle signal structures that are larger in intensity than the local background level. We suggest another filter structure which has the ability to preserve both positive and negative geometrical information with respect to the background level.
