Introduction

FTutor is software that provides educational tool for Fourier transform and its application in the field of digital image processing. It aims to attractively, yet clearly, explain how Fourier transform works, and uncover the potential that lies behind using this transformation. The software was designed and developed as a practical part of Petr Sečkář's bachelor thesis and master thesis .

The application is designed to present and teach Fourier transform easily and intuitively. It performs Fast Fourier Transform on a selected image, and displays its frequency spectrum. It allows user to modify the spectrum using various methods, and it performes Inverse Fast Fourier Transform to display result of the modification.

Fig. 1: User interface of FTutor. Shows selected image, spectrum of its transformation, modified image after inverse transformation and also currently selected frequency.
