Selection of Appropriate Methods for Classifying Pictures and Generating Chord Progressions to Introduce Tourist Destinations
Abstract
This study provides the following two methods applying the 2D FFT (fast Fourier transform) algorithms: (1) a method for finding pleasant photographs of local tourist destinations based on the results of a preliminary experiment, and (2) a method for generating chord progressions from these photographs considering the two kinds of “intervals”: (a) the difference between the frequency components and (b) the difference between pitches in music theory. Some examples are provided to illustrate the proposed methods.
