Abstract
Due to the increasing number of applications of digital image processing in the last years, we have included a course on tlus topic in the list of courses offered by the Electrical Engineering Department. This course has been taught at graduate level, however, undergraduate students at senior level are allowed to take it as an optional course. An educational software package has been developed to be used as a complement of the theory revised in the lectures. This package was implemented in Visual Basic*, which is a visual programming language to create applications in a Windows* environment. The image to be processed can be generated using the editor included, or can be imported using images in a bmp format. The images consist of a 64x64 pixels array with 16 gray levels. This size was considered enough to perform, with educational purpose, most of the operations in the spatial and frequency domains in a reasonable amount of time. Operations available include manipulation in the space and frequency domains, such as 2-D convolution, gray level transformations: linear filtering, histogram equalization, morphological filtering, and others. Examples show how the package can be useful as a lecture aid and as a lab assistance tool. The image to be processed can be generated using the editor included, or can be imported using images in a bmp format. A graphical interface allows the user to activate available operations through a menu selection. * Visual Basic and Windows of Microsoft, Inc.
