About this document
Image Sharpening with Butterworth Filter by Sonys_ITATS is a document available to read on EtoBox.
This document summarizes and compares Gaussian and Butterworth filters for image sharpening. It defines Gaussian and Butterworth low-pass and high-pass filters in both the frequency and spatial domains. In the frequency domain, Gaussian filters attenuate frequencies gradually rather than cutting them off abruptly, avoiding ringing artifacts. Butterworth filters also have a gradual transition controlled by the filter order. The document shows examples of applying Gaussian and Butterworth low-pass and high-pa
