1.	What is the maximum area of the cluster that can be eliminated by using an n×n median filter?(a) n^2(b) n^2/2(c) 2*n^2(d) nThe question was asked in an online interview.I would like to ask this question from Smoothing Spatial Filters in division Intensity Transformations and Spatial Filtering of Digital Image Processing
Answer» Correct CHOICE is (B) n^2/2 Explanation: Isolated clusters of pixels that are LIGHT or dark with respect to their neighbours, and WHOSE area is less than n2/2, i.e., half the area of the filter, can be eliminated by using an n×n median filter.
