Learning digital image processing concepts with simple Scilab graphical user interfaces

Abstract

Digital Image Processing is an extraordinary and fascinating world. However, to discover its enchantments it is necessary first to understand its fundamentals and its formulations. In this article, we intend to describe a set of simple Graphical User Interfaces (GUIs), developed in Scilab and using the “Scilab Image and Video Processing Toolbox” package. These interfaces aim to facilitate the learning of concepts of an Image Processing course, as well as to promote the interest of students. The GUIs described in this article include the transformation of truecolor into grayscale images, manipulation of grayscale images using radiometric transformations, histograms, spatial and frequency domain filtering, image restoration and image segmentation.
