Discuss the limiting effect of repeatedly applying a 3 x 3 lowpass spatial filter to a digital image. You may ignore border effects.
2. (a) It was stated in Section 3.5.2 that isolated clusters of dark or light (with respect to the background) pixels whose area is less than one-half the area of a median filter are eliminated (forced to the median value of the neighbors) by the filter. Assume a filter of size with n odd, and explain why this is so
(b) Consider an image having various sets of pixel clusters. Assume that all points in a cluster are lighter or darker than the background (but not both simultaneously in the same cluster), and that the area of each cluster is less than or equal to In terms of n, under what condition would one or more of these clusters cease to be isolated in the sense described in part (a)?
