Enhancing images using Fourier Transform

In the previous blog, I have partly shown some applications of Fourier transform such as edge detection, template matching, etc. Here we show another application which is image enhancement.

Fourier Transform and its applications

The Fourier Transform is a method of converting a signal of dimension X to a signal of dimension 1/X. This method gives way to analyzing signals in terms and their frequencies  and provides an easy mathematical manipulation of functions.

Here we discuss the basic implementation of Fourier Transform in Scilab and its applications to images. Continue reading “Fourier Transform and its applications”
