Question

What does using a mask having central coefficient maximum and then the coefficients reducing as a function of increasing distance from origin results?

(a) It results in increasing blurring in smoothing process

(b) It results to reduce blurring in smoothing process

(c) Nothing with blurring occurs as mask coefficient relation has no effect on smoothing process

(d) None of the mentioned

The question was asked in an interview.

I'm obligated to ask this question of Smoothing Linear Spatial Filters in portion Intensity Transformations and Spatial Filtering of Digital Image Processing

Answer 1

Right option is (a) It results in increasing blurring in smoothing process

Easy explanation: Use of a mask having central coefficient maximum and then the coefficients reducing as a function of increasing distance from origin is a strategy to reduce blurring in smoothing process.
