Extension of EasyPAS software for the learning of image and audio digital processing

This article describes the extension of easyPAS software for audio and image. EasyPAS is an educational tool in the scope of digital image processing and audio signals for both undergraduates and postgraduates. The extension is intended to be an independent learning system where the student can carry out the mathematical and graphical study in Octave/Matlab for the analysis and processing, of musical effects for example, as well as detections of contour or calculation of negatives on images. In addition, from the examples contributed to the application, where the characteristic parameters of each system will be varied to evaluate their effect, the student will be able to develop new plugins with problems and a new simulated audio and image system in Octave/Matlab. These plugins will be in XML or Java format.
