The analysis of fractaltexture reflects a change in pixel intensity, and this might contain information about the structure of objects since a great change in intensity might usually indicate changes in the object. In the images of banana surfaces, the textureimage can, to some extent, reflect changes and thus it can be used as an indicator of the last stage during the ripening process (over-ripening). In this experiment, bananas (Musacavendish) were stored during 10 days at 20 °C. Images of banana surfaces were recorded using a computational vision system. The over-ripening process of bananas was represented by an increment in the fractal value derived from texturefractalFourier analysis. The result shows that fractaltexture derived from the spectral Fourier analysis increased monotonically and it can be used as an indicator of the senescence process also called “senescentspotting” of the banana peel.
