Availability of interactive tools is essential for assisting students in visualization and understanding of the image-processing concepts. The latest technological advances, in particular HTML5 and Javascript, offer an opportunity to develop demos of basic operations in image-processing, like digital filters morphological operators, edge detection or feature detections. The goal of this project is to build a generic environment for Internet allowing development of a set of interactive demos. At the end, the work will be made freely available through our web server.
