Abstract

The digital image processing is widely studied in the scientific literature. Techniques for image treatment derived from satellites are continuously developed and improved. Although most of these techniques are readily available to the researchers, it is known that a minimum knowledge in programming should be purchased by those who wish to use these techniques. In this context, this paper proposes an open source graphical application which refers to preprocessing of images coming from satellites. The main focus is to become simple the use of preprocessing techniques without requiring the user to have knowledge about programming. To achieve this goal, technologies such as Qt framework (used for the development of graphical interface) and TerraLib (used for the development of preprocessing techniques) were used together and Façade design pattern was chosen to perform the communication between the technologies. This design pattern consists of developing a single interface to access resources developed and available in TerraLib library. The communication between the technologies is explained in detail and this work concludes with expectations about the proposal graphical application.
