1.	Two filters of similar size are used for smoothing image having impulse noise. One is median filter while the other is a linear spatial filter. Which would the blurring effect of both?(a) Median filter effects in considerably less blurring than the linear spatial filters(b) Median filter effects in considerably more blurring than the linear spatial filters(c) Both have the same blurring effect(d) All of the mentionedI got this question in an interview for job.This key question is from Smoothing Nonlinear Spatial Filter in chapter Intensity Transformations and Spatial Filtering of Digital Image Processing
Answer» Correct choice is (a) Median filter EFFECTS in considerably less blurring than the LINEAR spatial filters For explanation: For IMPULSE NOISE, median filter is much effective for noise reduction and causes considerably less blurring than the linear spatial filters.
