What is Smoothing vs. Sharpening in Filters about?

This document discusses frequency domain filtering techniques for image processing. It introduces ideal and Gaussian lowpass filters, which smooth images by attenuating high frequency components. It also introduces ideal and Gaussian highpass filters, which sharpen images by enhancing edges and details. The effects of varying the cutoff frequencies for these different filters on an example image are demonstrated and described. Specifically, lowpass filters cause blurring that decreases with higher cutoffs,
